I understand how to make Stem-and-Leaf plots,but I don't understand what to count by if my numbers are (from least to greatest) 13,14,16,18,20,32,33,52,58,61,and 67.Please help me!!!
To create a stem-and-leaf plot, you need to decide on a unit or counting interval. The counting interval determines how many stems will be in the plot and how many leaves each stem will have.
In your given data set: 13, 14, 16, 18, 20, 32, 33, 52, 58, 61, and 67, the smallest value is 13 and the largest value is 67.
To determine the counting interval, subtract the smallest value from the largest value and divide by the number of stems you want. Let's say we want to have 4 stems.
So, (67 - 13) / 4 = 13.5
Since the counting interval is not a whole number, we can round it up to the nearest whole number, which would be 14.
Now, let's create the stem-and-leaf plot:
The stem represents the tens digit, and the leaf represents the ones digit:
1 | 3 4 6 8
2 | 0 0
3 | 2 3
5 | 2 8
6 | 1 7
In this stem-and-leaf plot, the stem goes from 1 to 6, and each stem has corresponding leaves. For example, the stem 1 has leaves 3, 4, 6, and 8.
To read the plot, find the stem (the tens digit) and then read the leaves (the ones digit) in ascending order.
So, for example, the number 13 has a stem of 1 and a leaf of 3. The number 20 has a stem of 2 and a leaf of 0.
