Population Correlation Assignment | Professional Writing Services
A social scientist wishes to determine whether there is a relationship
between the attractiveness scores (on a 100-point scale) assigned to college students by a panel of peers and their scores on a paper-and-pencil test of anxiety.
The data is quantitative since they are based on attractiveness scores and anxiety scores.
Suppose a number of students are selected. A social scientist wishes to determine whether there is a relationship between attractiveness scores (on a 100-point scale) and their scores on a paper-and-pencil test of anxiety. We have 3 groups of 3 observations on each student and the observations are paired and hence not independent.
Therefore, apply the t-test for the population correlation coefficient in testing whether there is any relation between the paired observations of the attractiveness scores. And their scores on a paper-and-pencil test of anxiety. Assume the relationship between the 2 variables can be described with a straight line and that the sample originates from a normal bivariable population in applying the t-test for a single correlation coefficient.
t for a correlation coefficient
The observational study, no manipulation of variables. Compare data.
