Question

11.1 Describing a Multiple Regression. To minimize the negative impact of math anxiety on achievement in a research design course, a group of researchers implemented a series of feedback sessions, in which the teacher went over the small-group assignments and discussed the most frequently committed errors. At the end of the course, data from 166 students were obtained. The researchers investigated how students’ results were explained by math course anxiety, math test anxiety, numerical task anxiety, enjoyment, self-confidence, motivation, and perceived usefulness of the feedback sessions.

1. What is the response variable?
2. What are the cases and what is n, the number of cases?
3. What is p, the number of explanatory variables?
4. What are the explanatory variables?

Answer 1

In this problem, researcher is wanted to how the student's results were explained by math anxiety in different levels

a) Here the response variable is that students results

b) Here we are studying 166 student's cases, so n = 166

c) number of explanatory variables p= 7

d)* math course anxiety,

* math test anxiety,

* numerical task anxiety,

* enjoyment

* Self confidence

* Motivation

* Perceived usefulness of feedback section

These are the explanatory variables.

Thank you.
