Question

create a frequency chart of the data below using 2 - 4 as the first interval: 2, 4, 10, 6, 3, 9, 11, 12, 2, 3, 7, 7, 4. if the first interval is 2 - 4, what will the second interval be? 5 - 7 7 - 12 5 - 6 5 - 10

Explanation:

Step1: Determine interval pattern

Intervals should be consecutive and of equal width. First interval is 2 - 4, width is 2.

Step2: Find next interval

Add the width to the upper - limit of the first interval. 4+1 = 5, and with width 2, the second interval is 5 - 7.

Answer:

5 - 7
