You entered a number set X of {-6,4,3,-9,2,8}

From the 6 numbers you entered, we want to build the Frequency Distribution Table:
Determine the Number of Intervals using Sturges Rule:
We need to choose the smallest integer k such that 2k ≥ n where n = 6
For k = 1, we have 21 = 2
For k = 2, we have 22 = 4
For k = 3, we have 23 = 8 ← Use this since it is greater than our n value of 6

Therefore, we use 3 intervals
Our maximum value in our number set of 8 - -9 = 17
Each interval size is the difference of the maximum and minimum value divided by the number of intervals
Interval Size =17
3

Add 1 to this giving us 5 + 1 = 6
