Understanding Exercise Data Analysis

Arthur is investigating how his exercise routine affects his weight. He records weekly exercise hours and weight changes, aiming to create a scatter plot. The exercise hours, as the independent variable, should be on the horizontal axis, while weight change, the dependent variable, should be on the vertical axis. The exercise data ranges from 0.3 to 8.9 hours, so the axis should span from 0 to 10 hours.

What is Arthur trying to understand through his investigation?

• The relationship between age and fitness

• The influence of sleep on mood

• The impact of exercise on weight

• The effect of diet on weight

In a scatter plot, where should the independent variable be placed?

• On the vertical axis

• On the diagonal axis

• On the horizontal axis

• On the secondary axis

What is the maximum number of exercise hours Arthur recorded?

• 9.5 hours

• 6.2 hours

• 8.9 hours

• 7.5 hours

What is the minimum number of exercise hours Arthur recorded?

• 0.8 hours

• 0.3 hours

• 0.5 hours

• 1.0 hours

Why does Arthur decide to set the exercise axis range from 0 to 10?

• To include all data points

• To simplify calculations

• To match the weight axis

• To avoid negative values

Why is there no need for negative values on the exercise axis?

• Exercise hours can be negative

• Exercise hours cannot be negative

• Negative values are for weight

• Negative values are irrelevant
