Question

Each day, Boris records the number of news articles he reads. Here are his results for the last nine days.

3,4,4,9, 1, 4, 4, 1,4
Find the range and the mode for the data.

Answer 1

range= difference between highest and lowest number. 9-1=8. Range is 8
Mode = number that occurs the most. 3 occurs once, 4 occurs 5 times, nine occurs once, and 1 occurs twice. Thus, the mode is 4

Answer 2

range: 8

mode: 4

Explanation:

the range would be the difference between the greatest and least value in a data set_ so 9-1=8

the mode is the number that appears most often_ which would be 4 since it appears 5 times
