Today more than ever, a good grasp of quantitative data analysis techniques is a requirement for progression in both the academic and professional arenas. Note that we designed this guide to answer questions that teachers, students, corporate professionals, and researchers frequently ask if you need to improve your data analysis skills using IBM’s SPSS Statistics. So, without much further ado, let us dive straight into it!

What is SPSS, and How Do You Use It?

What is the full meaning of SPSS? SPSS is an acronym for IBM’s suite of statistical analysis software that stands for Statistical Package for the Social Sciences. It is one of the most popular statistical data analysis application which provides simple, comprehensive, and uncomplicated data analysis features.

SPSS History

In the late 1960s, three Stanford University students Dale H. Brent, C. Hadlai, and Norman H. Nie developed the original application known today as SPSS. At that time, they needed to analyze large volumes of statistical social science data. In 2009, IBM acquired the application renaming it to IBM SPSS Statistics. Initially, the application ran on punch card-based computers. However, today, it is available for use on Linux, Mac, and Windows client systems.

Core SPSS Functions

Given the complexity of working with statistical data, SPSS is a potent tool for process research and mission-critical data sets. As such, its core function facilitates the analysis, manipulation, transformation, and production of patterned data sets from raw quantitative data. Besides that, users can visually represent outputs using visual illustrations, including graphs, charts, custom, and pivot tables.
 Below is a snapshot of SPSS’s four core modules:

SPSS assignments

1. Modeler Module

This SPSS module allows researchers to build and validate predictive data models using advanced statistical procedures.

2. Statistics Module

SPSS’s inbuilt statistics module offers a plethora of data analysis and manipulation functions. With these functions, users can perform bivariate (ANOVA), cross-tabulation, descriptive ratio, frequency, correlation, non-parametric tests, linear regression, cluster analysis, and factor analysis.

3. Text Analytics for Surveys Module

With this module, survey administrators obtain authoritative insights from collected survey data.

4. Visualization Designer

This module simplifies the creation of visuals from statistical data, for example, radial boxplots and charts.

Apart from that, SPSS supports case selection, data derivation, and file reshaping functionality. Also, its data documentation feature allows for the creation of a metadata dictionary, a centralized repository of information about data (meaning, relationships, origin, usage, and formats).

In the next section, we answer the question of how SPSS is used in research?

Importance of SPSS In Research and Data Analysis

SPSS’s emphasis on the analysis of statistical data makes it a potent tool for deciphering and manipulating massive volumes of quanteitative data. As such, both qualitative and quantitative researchers can benefit from exploiting SPSS’s powerful tools, features, and functionality for data analysis activities.  SPSS’s drag and drop graphical user interface eliminates the stress involved during data analysis.

Before writing the conclusion section of research papers, scholars must analyze research findings. Usually, data analysis occurs in the fourth section of a scientific paper or project. Using SPSS shortens the time required to analyze data with minimal errors. Users also enjoy flexibility in visualizing outputs that represent the distribution of research data. What is more, the application can process both quantitative and qualitative data, further reducing a scholar’s workload. For this reason, SPSS is an essential application for researchers in the social sciences and other domains.

How to Use SPSS for Data Analysis

Although most users find using SPSS challenging, it offers extensive control over the data analysis process in several different ways. Both its syntax and GUI modes integrate seamlessly with other data analysis tools such as Python, RStudio, and more. As a result, researchers spend more time analyzing data instead of concentrating on routine commands and steps.

Below are a few factors that demonstrate the importance of SPSS as a research and data analysis tool.

ANOVA (Analysis of Variance)

ANOVA is a statistical technique for determining variations between groups, processes, or events by comparison. Through this approach, researchers can identify the most suitable method for performing a specific task. By evaluating the results of ANOVA, one finds out the effectiveness and feasibility of a technique.

Data Transformation

A technique that facilitates the conversion of data from one format to another. After data conversion, the application integrates related data into a single place, simplifying the data management process. With SPSS, one can input and transform different types of data using predefined criteria and system specifications. For researchers or data analysts, this is a plus as SPSS can process converted data regardless of the underlying operating system.

MANOVA (Multivariate Analysis of Variance)

MANOVA is a statistical data analysis technique that compares unknown random data variables. For instance, with MANOVA, you can analyze different population samples as well as the factors affecting their preferences.

Regression Analysis

A data analysis technique used to comprehend the relationships between dependent and interdependent data variables residing in a data file. Regression analysis also helps researchers understand how variations in the value of interdependent variables affect dependent variables. Primarily, the goal of regression analysis is to identify relationships between different variables.

T-tests  

An approach used in data analysis to determine differences between two samples. Researchers typically employ T-tests to differentiate the interests of groups. T-tests also help researchers establish the relevance or irrelevance of a derived output.                            

Using SPSS: Step by Step Guide

SPSS uses a spreadsheet-like layout to display data. A core principle of entering data into the application entails inputting each unique case into a new row. A case is a research entity, for example, an individual, products, or services. But in this piece, we assume that a case equates to an individual. Always input an individual’s data into one row. If a case’s data appears in multiple rows, there is a mistake. Equally, if a row contains more than one person’s data, it is a mistake too.

So, let us look at the most common tasks for entering data into SPSS, creating SPSS datasets, and converting Excel data into the SPSS format.

  1. Manual Data Entry

Step # 1 Defining Variables

Before you begin entering data, you must define the variables. Below is the procedure for defining a variable:

  • Upon launching SPSS, it presents a spreadsheet layout called the Data View. Each is designed to hold data sharing the same format.
  • Double click a columns header to open where you enter a variable’s name
  • Always begin a variable’s name with a letter through SPSS is not case sensitive.
  • Next, assign a data type to a variable. Possible data types include string or numeric (several varieties).

Step # 2: Defining A Multiple-Choice Variable

Sometimes you will need to work with variables with multiple sets of possibilities. To define variables of this type, assign unique labels to a variable’s value. An example is where you need to determine whether an employee is active or fired. Here, you have only two values active and former.

  • Use the Labels section of the Define Variable menu and input a numeric value for each possibility (1, 2 and so on)
  • Assign a corresponding label to each value (active, former).
  • Now, to enter data for that variable, you only need to type 1, 2 to select that value you want

Step # 3: Entering Cases

Click an empty cell on the leftmost column of the Data View windows. Enter a value that matches the variable’s data type in the cell. For example, if a column has the label name, input an employee’s name in the corresponding cell.

  • Remember that SPSS treats each row as a “case” like records in a database.

Step # 4: Fill Out All Variables

Next, move to an empty cell on the right and input appropriate data values. Even so, be careful when entering your data. Always enter a complete case at a time. An example record consists of employee name, address, phone, salary, and status.

  • Ensure that all inputs match the defined data type of the specified variable. For instance, inputting currency values in a date formatted field will result in an error.

Step # 5: Complete All Cases

After finishing with a case, move down to a row below it and fill out the next case. Make sure that every defined variable contains data before proceeding to a new one.

  • If you need to create another variable, simply double click a column header and label it.

Step # 6: Manipulating Data

Once you are done entering data, you can use SPSS’s in-built functionality to manipulate data. Some example of operations you can perform on data include:

  • Build frequency tables
  • Perform regression analysis on your data
  • ANOVA
  • Create scatter plot graphs

2. Importing Data

A second method of entering data into SPSS is importing. This process involves acquiring preprocessed data from another program, for example, Access, Excel, FoxPro, SQL Server, Oracle, dBase, Lotus, Sylk, SAS, MyStat, and Stata. Follow these steps to import data into SPSS:

Step # 1: Import Excel data

Importing data from an Excel file automatically creates variables using a spreadsheet’s first row. These values become variable names. Besides that, you can still define variables manually if necessary.

  • Launch SPSS
  • Click File, Open, Data.
  • Navigate to the location where your .xls, .xlsx, or .xlsm file resides.
  • Select the file to import.
  • Tick the “Read variable names from the first row of data checkbox to create variable names automatically.

Step II: Import Comma-Separated Value File

Comma-separated value files are plain text-formatted files. Similarly, you can create variable automatically using the first line of a .csv file. Here is the import procedure:

  • Click File, Open, Data.
  • Select All Files in the “files of type drop-down list
  • Browse for the .csv file and click the Open button
  • Follow onscreen prompts to import the data. However, let SPSS know that variable names are at the top of the file when requested and indicate that the first case begins on the second line.

Creating Files and Data Sets In SPSS

  • Upon launching SPSS, it displays a blank spreadsheet in Data View mode. If you have another dataset open and need to create a new one, click File, New, Data. Doing so opens a blank spreadsheet.
  • Then, follow the steps highlighted on SPSS’s screen.
  • Finally, you need to save your dataset. To do so, select File, Save.
  • Provide a meaningful name for the created dataset and press the Save button.
  • And there, you just created a new SPSS data set!

Learning to Use SPSS

Given SPSS’s ability to process large and complex datasets, you might ask how can I learn SPSS fast? So, let us dive into the basics!

We strongly recommend finding a research project or enrolling for an online course. Some of us can read books and manuals to understand what SPSS is all about. But we might need to ask questions when we get stumped. Keep it in mind that SPSS and most statistical applications handle data differently. Therefore, you might find it challenging denoting which functions, features, and tests are significant unless you have a background in statistics. Besides, you might not know how to interpret the results of your analysis.

For this reason, first, ground yourself in statistics. Doing so will help you analyze all forms of statistical data using SPSS with confidence. Also, you gain useful skills for planning an independent research study from the beginning. Next, obtain a good SPSS reference book and statistical study book.

Of course, you need access to SPSS. Hence, ensure you have it installed on your PC or Mac. If you are at a university or organization, your system administrator will help you set it up. From this point on, learning SPSS is mostly self-explanatory. Any time you need assistance, just click “Help “to access context-sensitive assistance on a specific command. Armed with an authoritative SPSS guide, YouTube videos, and a licensed copy of SPSS, you are well on your way to mastering this data analysis tool.

Why Is SPSS Better Than Excel?

Although SPSS and Excel share similar features such as menus, spreadsheets, and built-in statistic functions, SPSS is the winner. Excel is a spreadsheet application, while SPSS is a de facto statistical data analysis tool. Here we present several fundamental reasons why SPSS is the better tool for data analysis.

How to Use SPSS for Data Analysis 1

In-Built Error Handling and Prevention

With SPSS, users need not worry about overwriting data by accident. Sorting errors are common in Excel worksheets. Why is that so? Because SPSS assigns unique record IDs (primary keys) like database management applications. Its use of primary keys minimizes the occurrence of sorting errors and record duplication. Effective use of functions in Excel depends mainly on a user’s mathematical knowledge. In spreadsheets, errors occur whenever users copy data or formulas wrongly, especially when inserting columns or rows. SPSS does not require users to enter formulas. Also, SPPS keeps data and results separate from each other, minimizing the risk of damaging data. As a result, it is easier to automatically detect errors which are often localized in scope and syntax.

SPSS Is More Potent Than Excel

Although one can use Excel to perform statistical analysis, SPSS is more powerful. Its plethora of inbuilt data manipulation tools are not available in Excel. Analyzing statistical data using Excel is a tasking undertaking for non-tech savvy scholars, data analysts and other users. Even though Excel is superb in its organization of data, the power of SPSS provides users with profound, fast, and accurate data analysis features.

Data Visualization

Despite Excel’s popularity, it has limited graphical data presentation features. In contrast, SPSS simplifies the data visualization process using built-in charts. These charts include box lots, stem leaf, Pareto, and others, which extends an analyst’s ability to present visual data in ways that Excel cannot.

Thorough Data Management

SPSS has optimal data organizing features, for example. It represents rows as a case with columns denoting a single variable. This feature speeds up the data entry and analysis process as SPSS knows the location of all cases and variables. With Excel, users must define this relationship manually for every analysis. Besides that, SPSS provides a data trail, which makes it easy for users to retrace the exact steps they took to analyze data.

Output Organization

SPSS stores output and data files separately. So, its users never have to worry about overwriting data by mistake. In comparison, excel stores results of the analysis in a single worksheet further increasing the possibility of data loss or corruption.
