Week 4 Jasp file

Load the attached file in JASP and perform the proper test to determine if there is a significant difference in the Degree of Reading Power for the control group and the treatment group to determine if the Directed Reading Activities treatment was successful. The variable descriptions and research overview are attached below.

First, use JASP to determine if the assumptions have been met.

• Use the Shapiro-Wilk test to determine if the data are normally distributed.
• Use Levene’s Test to test for homogeneity of variances.
• Based on the results of normality and homogeneity of variances, choose the correct statistical technique to test the hypothesis that there is a significant difference between the control and treatment groups.

Perform the correct test of means and include the location parameter with 95% confidence interval, the effect size, descriptives, descriptive plots, and raincloud plots.

Add your name to the module and use the results to answer the following questions. Round your answers to three decimal places as they are in JASP.

Q1a. What is the W-statistic for the Shipiro-Wilk?

Q1b. What is the F-statistic for Levene’s test?

Q1c. What is test statistic for the hypothesis test?

Q1d. What is the mean difference for the control and treatment groups?

Q1e. Based on the results, was the Directed Reading Activity successful (yes/no)?

Load the attached file in JASP and perform the proper test to determine if Recall is significantly greater for Fixation (Group 1) than for Horizontal Eye Movement (Group 2). The variable descriptions and research overview are attached below.

First, use JASP to determine if the assumptions have been met for the proper test of means.

• Use the Shapiro-Wilk test to determine if the data are normally distributed.
• Use Levene’s Test to test for homogeneity of variances.
• Based on the results of normality and homogeneity of variances, choose the correct statistical technique to test the hypothesis that there is a significant difference between the control and treatment groups.

Perform the correct test of means and include the location parameter with 95% confidence interval, the effect size, descriptives, descriptive plots, and raincloud plots.

Add your name to the module and use the results to answer the following questions. Round your answers to three decimal places as they are in JASP.

Q1a. What is the F-statistic for Levene’s test?

Q1b. What is the test statistic for the hypothesis test?

Q1c. What are degrees of freedom for the test statistic?

Q1d. What is the mean difference for the control and treatment groups?

Q1e. What is the effect size?
