Answer:
Mean: 22
Median: 21
Mode: No mode
Step-by-step explanation:
<u>Mean:</u>
The sum is the value of all the values divided by the number of values:
which is 22.
<u>Median:</u>
The median is the middle-most value of the data set when arranged from lowest to highest:
13, 16, 19, 20, 22, 25, 30, 31
Here, since there are two middle-most terms, the median would be the average of 20 and 22 (20+22/2), which is 21.
<u>Mode:</u>
The mode is the most occurring value in the data set.
13, 16, 19, 20, 22, 25, 30, 31
Since, in this data set, there is do value that occurs twice, we can say that there is no mode for this data set.
