inferential stats

Part 1 – Paired Samples t-Test
Sandbox Scenario 1
As you begin to take a closer look at the sixth grade language arts issues, you observe that there are twenty students enrolled in a remedial reading program. Several of the teachers who you surveyed questioned whether this program was effective because this was the program had been handed to them by administration. This point of contention continues to make them disgruntled. Since no quantitative analysis had ever been conducted to determine the reading program’s efficacy, you make a decision to design a study so that finally, a determination can be made about whether the reading program is effective. Specifically, you are going to conduct inferential statistics to determine if the remedial reading program actually helped improve reading scores. The students’ reading scores before and after the intervention are shown in the dataset provided.

Instructions
Using the dataset provided, conduct statistical analysis to test the following null hypothesis and post your results to the discussion activity for this week.
There is no statistically significant difference between students’ reading scores before and after the intervention is provided to students.
Your results will indicate that you either will reject the null hypothesis when there is a significant difference or you will fail to reject the null hypothesis when there is no significant difference.
Dataset Legend
The following legends are used in the sandbox dataset.

Gender: 0 = Male; 1 = Female.
Race: 1 = Asian/Pacific Islander; 2 = African American; 3 = Hispanic/Latino; 4 = White/Caucasian.
Socioeconomic status (SES): 1 = 75,000–100,000; 2 = 50,000–69,999; 3 = 20,000–49,999.
School type: School 1 and School 2.
Academic program: 1 = program 1; 2 = program 2; 3 = program 3
Part 2 – Independent Samples t-Test
Sandbox Scenario 2
As you continue your analysis of the sixth grade language arts issues, you are contacted by the district math specialist who wants your help in determining whether there are significant differences in the sixth grade math placement scores based on gender. Because of your expertise in research design, you help the math specialist design a study in which 50 students (25 males and 25 females) are selected who completed the sixth grade math placement exam.

Instructions
Using the dataset provided, conduct statistical analysis to test the following null hypothesis and post your results to the discussion thread:
There is no statistically significant difference in the math scores when the scores are grouped and compared by gender.
Your results will indicate that you either will reject the null hypothesis when there is a significant difference or you will fail to reject the null hypothesis when there is no significant difference.
