An experiment was conducted to examine the effect of age on heart rate when a person is subjected to a specific amount of exercise. Ten men randomly selected from each of four age groups: 10-19, 20-39, 40-59, and 60-69. Each man walked a treadmill at a fixed grade for a period of 12 minutes, and the increase in heart rate (the difference before and after exercise) was recorded (in beats per minute). The data are shown in the table. An experiment was conducted to examine the effect of age on heart rate when a person is subjected to a specific amount of exercise.

Kruskal-Wallis H Test

A nonparametric statistical test designed to assess whether there's a significant difference between two or more groups related to an independent variable, with respect to a continuous or ordinal dependent variable.

Heart Rate

The number of times the heart beats per minute, a vital sign used to assess the general physical health of an individual.

Age Groups

Categories of individuals segmented according to their ages, often used in research and demographic studies.

  • Initiate the Kruskal-Wallis test to identify differences between more than two entities.
  • Analyze the evidence and decisive factors of nonparametric tests.
