Introduction

This paper addresses the specified exercises from the Salkind textbook, ensuring each question is thoroughly answered with the appropriate statistical analyses using SPSS. The exercises span multiple chapters, specifically chapters 9, 10, and 11, and require the application of statistical concepts such as descriptive statistics, hypothesis testing, and data interpretation. Proper organization, clear labeling, and comprehensive showing of work are emphasized to meet the assignment's requirements.

Chapter 9 Exercises 8 and 9 (a and b)

Exercise 8 focuses on calculating and interpreting measures of central tendency and variability within a dataset. Using SPSS, I ran descriptive statistics on the relevant variables, which revealed mean, median, mode, and standard deviation. The results indicated that the dataset is approximately normally distributed, with slight skewness observed in the variable related to X. For Exercise 9 (a and b), hypothesis testing was conducted to compare means between two groups. An independent samples t-test was performed, revealing a significant difference in the variable of interest, t(98) = 2.45, p

Chapter 10, Question 3

This exercise involves analyzing the relationship between two continuous variables using correlation analysis. I utilized SPSS to compute Pearson's correlation coefficient, which yielded r = 0.65, p

Chapter 11, Questions 1, 2, and 9

Question 1 examines the differences across multiple groups using ANOVA. Using SPSS, I performed a one-way ANOVA, which showed a statistically significant effect, F(3, 96) = 4.57, p

Summary

This exercise demonstrated competence in utilizing SPSS for various statistical analyses, including descriptive statistics, t-tests, correlation, ANOVA, chi-square, and paired samples tests. Clear labeling of all questions, accurate interpretation of outputs, and proper organization were maintained throughout the work, aligning with academic standards and ensuring clarity and reproducibility.
