Can you help Find the mean of the data set.

Find the mean of the data set.
94, 90, 88, 66, 94, 81, 102, 108, 88

Find the median of the data set.
94, 90, 88, 66, 94, 81, 102, 108, 88

mean and median, and also mode, are the measurements of central tendency(MCT)

Mean is the average. so just add all of them then divide it by 9. you should get, 90. your unit of measurement should be the same as your raw data. thus, it should also be to the nearest ones.

median is the center. to get this, arrange first the raw data from smallest to highest.
arranged numbers: 66, 81, 88, 88, 90, 94, 94, 102, 108
then get the median locator. the median locator is computed using the formula: (n+1)/2. n-number of raw data. in this case, (9+1)/2 =5th
the 5th data is the median. the median is 90.

notice that the median and mean are the same, but sometimes close.

the mode is the most frequent number. in the problem it is 88 and 94

mean means average basically, im guessing your taking data management.

mean = 94+90+88+66+94+81+102+108+88 /9

mean=90.11

median is the middle point of a set of values

94, 90, 88, 66, 94, 81, 102, 108, 88 rearrange it from low to highest

66, 81,88, 88, 90 , 94, 94, 102, 108

median is 90

The mean of the data is
= (94+90+88+66+94+81+102+108+88)/9
= 811/9
= 90.11
The mean of the data is 90.11

To find the median, we need to rearrange the data in ascending order.
66, 81, 88, 88, 90, 94, 94, 102, 108

To find the position of the median
= (n+1)/2
= (9+1)/2
= 10/2
= 5th score

Therefore, the median of the data is 90, which is the 5th score.

Mean = Sum of the values divided by the number of values. So

(94 + 90 + 88 + 66, 94 + 81 + 102 + 108 + 88) divided by 9 = 90.1

Median = The middle value, so you put 94, 90, 88, 66, 94, 81, 102, 108 and 88 in order, which is...

66, 81, 88, 88, 90, 94, 94, 102, 108 so the middle value, of median is 90.

Mean = total / number of terms
so it's 811/9 = 90.1 (3 sf)

Median = middle term when arranged in ascending order
so median = 90 (:

Hope that helped.
