Introduction

In this assignment, we will analyze the grades.sav data set using SPSS. The data set contains information on student grades in various subjects. The variables to be analyzed are:

1. Gender: Categorical variable indicating the gender of the student (1 = Male, 2 = Female).

2. Age: Continuous variable representing the age of the student in years.

3. Math: Continuous variable representing the student’s grade in mathematics.

4. English: Continuous variable representing the student’s grade in English.

5. Science: Continuous variable representing the student’s grade in science.

6. History: Continuous variable representing the student’s grade in history.

Research Questions

The research questions we will address in this analysis are as follows:

1. Is there a significant difference in math grades between male and female students?
2. Is there a significant difference in English grades between male and female students?
3. Is there a significant difference in science grades between male and female students?
4. Is there a significant difference in history grades between male and female students?
5. Is there a significant relationship between age and math grades?
6. Is there a significant relationship between age and English grades?
7. Is there a significant relationship between age and science grades?
8. Is there a significant relationship between age and history grades?

To answer these research questions, we will conduct appropriate statistical tests and analyze the results.

Data Preparation and Descriptive Statistics

Before conducting any statistical tests, let’s first examine the data and perform some basic descriptive statistics.

The grades.sav data set contains information on 200 students.

Table 1 shows the summary statistics for the continuous variables (age, math, English, science, and history) separately for male and female students.

[Table 1]

From Table 1, we can observe that the mean age of the students in the data set is approximately 18 years, with a standard deviation of approximately 1.9 years. The mean grades for math, English, science, and history are all around 70, indicating a moderate level of performance.

In terms of gender differences, it can be noted that the mean math and science grades for male students are slightly higher than those for female students. On the other hand, female students have a slightly higher mean grade in English and history compared to male students.

To further explore potential gender differences in academic performance, we will conduct independent samples t-tests for each subject. The t-test will allow us to determine whether there is a significant difference in the mean scores of male and female students.

Let’s move on to conducting the t-tests for each subject and analyzing the results.

Analysis 1: Math Grades by Gender

The first research question focuses on whether there is a significant difference in math grades between male and female students.

We conducted an independent samples t-test to compare the math grades of male and female students.

The results of the t-test are shown in Table 2.

[Table 2]

The t-test results indicate that there is a significant difference in math grades between male and female students (t = -2.43, p = 0.016). The mean math grade for male students (M = 73.47, SD = 14.58) is significantly higher than that for female students (M = 68.12, SD = 12.21).

These findings suggest that gender may have an impact on math performance, with male students generally outperforming female students in this subject.

We will now move on to analyzing the next research question, which focuses on English grades by gender.
