Question

I need help on this question plz answer me fast plz

Answer 1

Hello!

To find the mean, we will first want to order all of the numbers from least to greatest.

65, 72, 74, 75, 75, 75,86, 89,93,95, 95, 96,97, 100

Now we need to find the middle number. As there are 14, we find the mean of the two middle numbers.

86+89=175

175/2=87.5

Now we find our mode. This is the number that appears the most in the data set. As you can see, 75 appears 3 times.

Therefore, our mode is 75.

Our median is 87.5, and our mode is 75.

I hope this helps!

Answer 2

You compute the median as follows: order your elements in ascending order, and consider the element in the middle. The ordered dataset is

`65\ 72\ 74\ 75\ 75 \ 75 \ 86 \ 89 \ 93 \ 95 \ 95 \ 96\ 97\ 100`

And since there are 13 elements, the middle one is the seventh, which in this case is 86.

The mode is even simpler: it's the most recurring value. 75 occurs three times, which is the highest amount of repetitions, so it its the mode
