Answer: Mean: 20, Median: 29, Mode: 14, Range: 16
Explanation:
To know the mean, you have to add all the numbers and then divide it by how many numbers there are. So 13 + 21 + 14 + 29 + 26 + 14 + 23 is 140, then we divide 140 by how many numbers there are which in this case is 7 So 140 / 7 is 20. The median is the middle number which is 29. Mode is the most common number that shows up the most which would be 14. Hopefully this helps! :) P.S since you said you forgot the range, to define range you need to subtract the lowest value from the highest value, so the lowest value is 13 and the highest is 29. So if you subtract 13 from 29 you get 16.
