.Respond to the following short answer questions: D4.1 Interpreting Reliability. Interpret the interrater reliability and paired t test results for the ‘visualization test’ and visualization’ scores using Output 7.2. What might be another reason for the pattern of findings obtained besides those already discussed in Chapter 7? D4.2 Interpreting Validity. If one were to delete one of the 14 items in Output 7.3 based on factor analysis which one would it be? Explain your answer. D4.3 Interpreting Internal Consistency. Interpret the Chronbach alphas in Output 7.4 a, b, and c. What is the internal consistency reliability? Explain your answer.
Respond to the following short answer questions: D5.1 Interpreting Chi‐Square. In Output 8.1 is the (Pearson) chi‐square statistically significant? Explain your answer and what it means. Are the expected values in at least 80% of the cells greater than or equal to 5? Explain how you know and why it is important. D5.2 Measure Strength of the Relationship. Because ‘father’s education revised’ and ‘mother’s education revised’ are at least ordinal data, which of the statistics used in Problem 8.3 is the most appropriate to measure the strength of the relationship; phi, Cramer’s V, or Kendall’s tau‐b? Explain your choice. Why are the Kendall’s tau‐b and Cramer’s V different?
