Answer:
Step-by-step explanation:
In this stem and leaf plot, the number in "stem" combines with another number from "leaf" to form the real number they are referring to. For example, 1 | 0 becomes 10, and 2|3 becomes 23.
Step 1: List out all of the numbers
04= 4
4, 4, 7, 7, 8, 10, 12, 15, 16, 16, 23
Step 2: Find the range
Range= BIGGEST number - SMALLEST number
Biggest: 23
Smallest: 4
23- 4= 19
Step 3: Find the median
Median: Number in the middle
When i say this, I literally mean to line up all the numbers from least to greatest, and find the one in the middle.
4, 4, 7, 7, 8, 10, 12, 15, 16, 16, 23
Now, you count how many numbers there are. There are 11 numbers. and 11 is an odd number.
In this case, you have to find the middle number, which is 10. This is because there has to be an equal amount on numbers on both sides of the middle number. I like to place my finger on the middle number to cover it up and see how many numbers are to the left and to the right to make sure they are equal. When doing this, exclude the middle number.
Median= 10
Step 4: Find the mode
Mode= number that is seen the most times
Refer to the list:
4, 4, 7, 7, 8, 10, 12, 15, 16, 16, 23
4 appears 2 times
7 appears 2 times
8 appears 1 time
10 appears 1 time
12 appears 1 time
15 appears 1 time
16 appears 2 times
23 appears 1 time
The numbers that appear most are 4, 7, and 16. Since all 3 of the numbers are tied , appearing the same number of times, I will assume that 4, 7, and 16 are the modes.
Mode(s): 4, 7, 16
Hope this helps!! Also can i please get brainliest? I worked pretty hard on this :D
