Mean = 91
Median = 86
Mode = 98
Range = 11
a) Mean
To find the mean, we sum up the numbers and divide by the count
The count of the numbers is 6
We have the mean as;
[tex]\frac{98+98+90+82+89+87}{6}\text{ = }\frac{544}{6}\text{ = 90.67 which is 91}[/tex]b) To find the median, we will need to get the middle number
Since the count of the numbers is even, then we have two numbers at the middle
We have the median as the average of these two;
[tex]\frac{90+82}{2}\text{ = 86}[/tex]C) Mode
The mode is the highest in frequency (it means the number that re-occurs the most
The mode in this case is the number 98
d) Range
Range is the difference between the highest and smallest numbers
We have this as;
[tex]98-87=\text{ 11}[/tex]
