Data Analysis and Application

The objective of this paper is to assess the effect of caffeine use and exercise on heart rate. For that purpose, a Factorial ANOVA will be conducted. Specifically, the objective of the analysis is to determine whether caffeine usage (no caffeine versus 150 mg caffeine) and exercise (no exercise versus half an hour of exercise) have significant main effects on heart rate, along with determining whether the interaction of exercise and caffeine consumption have a significant effect on heart rate or not.

Data File Description

This file contains three variables, namely, Caffeine (1 = no caffeine, 2 = 150 mg caffeine), Exercise (1 = no exercise, 2 = half an hour of exercise), and HeartRate ( ratio variable). The dataset contains N = 16 valid cases. In the context of the analysis that will be performed, the variables Caffeine and Exercise will be the factors (or independent variables), and HeartRate will be the dependent variable.
