Description
D7.1 Interpreting Independent Samples t-Test. In Output 10.2, are the variances equal or significantly different for the three dependent variables? Explain your answer. Write the appropriate t, df, and p (significance level) for each t-test as you would in a dissertation. Which t-tests are statistically significant? Explain your answer. Write sentences interpreting the gender difference between the means of ‘grades in high school’ and ‘visualization’. Interpret the 95% confidence interval for these two variables. Discuss the effect sizes as you would in a dissertation.
D7.2 Interpreting Paired Samples t-Test. In Output 10.4, what does the paired samples correlation for ‘mother’s education’ and ‘father’s education’ mean? Interpret and explain the results of the t-test.
Explain how the correlation and the t-test differ in what information they provide. Describe the results if the r was 0.90 and the t was 0.00. Describe the results if the r was 0.00 and the t-test was 5.0.
