To graph the information into a frequency table, select an appropriate interval size that captures the range of the data. In this case, an interval size of 2 would be the most appropriate.
The correct answer to the given question is option A.
To graph the information into a frequency table, you need to determine an appropriate interval. The interval should be wide enough to capture all the data, but not too wide to lose important details.
To do this, find the range of the data (highest value minus lowest value) and divide it by the number of intervals you want.
In this case, the highest value is 7 and the lowest value is 2, so the range is 7 - 2 = 5. To determine the number of intervals, you can consider the options provided. A. 2 would divide the range into 2 intervals (5/2 ≈ 2.5), B. 4 would divide the range into 4 intervals (5/4 = 1.25), C. 10 would divide the range into 10 intervals (5/10 = 0.5), and D. 20 would divide the range into 20 intervals (5/20 = 0.25). Based on the options, option A. 2 would be the most appropriate interval size for this data.
