Find the mean, median, and mode of the following set.
27, 20, 34, 37, 21, 42, 39
mean: 31.4; median: 35.5; mode: 37
mean: 31.4; median: 34; no mode
mean: 36.7; median: 34; no mode
mean: 36.7; median: 37; no mode

i got the median, i only need the mode (if there is one)

We had:
27,20,34,37,21,42,39
We just need to order the number from least to greatest:
20,21,27,34,37,39,42
Means equal average which means that you had to all numbers divided with total numbers
Mean:31.4

Median means middle number. In this case, we only see one number which is 34
Median:34

Mode means that one number repeated many times,but we don't see any number in this repeated more than one times, which means there is no mode. Hope it help!

Ibelieve that c. recording would work best.
