Measures of Central Tendency

By: Braylee Koehl

The numbers that we are using.


5, 9, 7, 3, 10, 2, 8, 9, 11, 10, 6, 4


Minimum

The number with the lowest value in a set.

In this case it would be 3.

Maximum

The number with the greatest value in a set.

So your maximum will be 11.

Median

The middle number in a sorted set of numbers. Put in order least to greatest . Find the middle.

7 is the median.

Say there were 10 numbers and 5 and 7 were in the middle, you would have to add them together ( 5+7=12) then you would divide them by 2 (12 divided by 2 =6).

2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 11

Range

The difference between the minimum and maximum values .

Maximum: 11

Minimum: 2

11-2=9

So 9 will be your range.

Mean

The average of the numbers in a set.

Add all numbers

You have to divide the number of numbers the you have already added

5+9+7+3+10+2+8+9+11+10+6+4=84

84 divided by 12= 7

And you get your answer - 7.

Mode

The number that appears MOST often.

10 appears most out of the 12 numbers.
