Question

Using the set of numbers find the mean ( rounded to the nearest tenth ) , median , mode and range.

Answer 1

The mean is the sum of all data divided by the number of data.

You have 6 data:

Mean: 90.7$\frac{98+98+90+82+89+87}{6}=\frac{544}{6}=90.7$

-----------------------------------------------

The Median is the data in the middled of the data when the data is froms least to greatest.

$82,87,89,90,98,98$

In this case as the number of data is 6 you take third and fourth data and find the average (sum the data and divide into 2):

$\frac{89+90}{2}=89.5$Median: 89.5

----------------------------------

The mode is the data that appears the most:

Mode:98

----------------------

The Range is the difference between the largest and the smallest data.

$98-82=16$Range: 16
