Histogram Interval Width and Data Range

The video tutorial explains how to create a histogram with 25 data points ranging from 20 to 120. It recommends dividing the data into five intervals, each with a width of 20 units. This division is based on the range of 100, calculated by subtracting the minimum value from the maximum. The tutorial provides a step-by-step explanation of how to determine the interval width and the reasoning behind choosing five intervals for even distribution of data points.

What is the range of data points Joelle is working with for the histogram?

• 10 to 100

• 20 to 120

• 40 to 140

• 30 to 130

How many intervals are recommended for Joelle's histogram?

• 6 intervals

• 5 intervals

• 4 intervals

• 3 intervals

Why is it suggested to use five intervals for the histogram?

• To simplify calculations

• To evenly distribute the 25 data points

• To ensure each interval is 10 units wide

• To match the number of data points

What is the calculated interval width for Joelle's histogram?

• 25 units

• 10 units

• 20 units

• 15 units

How is the interval width determined from the data range?

• By dividing the range by the number of intervals

• By dividing the range by the number of data points

• By multiplying the range by the number of intervals

• By adding the range to the number of intervals
