APPLYING INFERENTIAL STATISTICS

Overview

This assignment introduces you to Paired Samples and Independent Samples t-Tests. For each type of t-test, you are provided with a sandbox activity to conduct the tests. You will have the opportunity to post the results of your practice t-tests as part of your discussion activity this week to receive feedback from your peers. 

Two Scenarios

At Madison Middle School, the sixth grade language arts teachers are unhappy with the curriculum. However, there’s a disconnect, as standardized test scores show improvement from previous years. You, a district reading specialist, have been called in to investigate the situation. Sixth grade reading scores have improved moderately from 2014 to 2018. These increases amount to 0.23 SD during the five year period for which reading scores were recorded. In general, a 0.50 standard deviation increase represents an increase from the 50th to the 69th percentile for data that are normally distributed. This compares to a percentile increase from the 50th to the 60th when the corresponding increase in standard deviation is approximately 0.25.

you made a decision to conduct in depth interviews with the language arts teachers. The purpose of this was to help the school decide if they would keep, replace, or modify the existing program. In your analysis, you identified codes, coding categories, and emergent themes. These were some of the conclusions that you made as a result of the thematic analysis included these observations:

· Teachers feel frustrated because they feel like this program was handed to them without their feedback or buy-in. The more experienced teachers seem like they might feel like this is condescending, and their expertise is being dismissed.

· Training teachers on how to implement the new curriculum seems to be a major issue. It appears that the faculty members who were tasked with conducting the training were not given enough time to do this effectively. Teachers feel like they aren’t able to get questions answered on whether they’re implementing the program correctly.

So now, in addition to the qualitative data you obtained and the corresponding analysis you conducted, you are re-visiting this issue and seeking to obtain quantitative data and analyze it in an effort to gain a more complete picture of the issues facing Madison Middle School.

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

1. 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

1. 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.

Dataset Legend

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.
