Given data set:
Murrr4er [49]

Answer:

mean =6, median =6.5  mode = 7

Step-by-step explanation:

mean =6, median =6.5  mode = 7

hello,

to find the mean, you add all the numbers together and divide it by the total number of numbers. so that would be 66(total sum) divided by 11 (number of numbers) to get 6.

to find the median, you would organize the numbers from least to greatest and find the middle number which is 6.5

last but not least, to find the mode, just look for the number that appears most often. Therefore, the mode would be 7.

hope this helped!
