Question

The data represent the time, in minutes, spent reading a political blog in a day Construct a frequency distribution 5 classes In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency? Complete the table starting with the lowest class limit. which class has the greatest frequency? The class win the frequency is from to Which class has the least frequency? The class win the least frequency is from to

Explanation / Answer

The data given in the question statement can be tabulated in the frequency table as below:

In the above table,

Midpoint for a class is calculated as: (Lower Class Limit + Upper Class Limit)/2

Relative Frequency = (Frequency of that class)/20

Class with greatest Frequency = 12-15

The class with greatest frequency is from 12 to 15

Class with least Frequency = 4-7

The class with least frequency is from 4 to 7

Reading Time Frequency Midpoint Relative Frequency Cumulative Frequency 0-3 6 1.5 0.30 6 4-7 0 5.5 0.00 6 8-11 6 9.5 0.30 12 12-15 7 13.5 0.35 19 16-19 1 17.5 0.05 20 Grand Total 20
