Finding the Median - Set 1

MMM 3

Instructions: Find the Median of each set below. Remember, the members must be in order and if there's an even number of members, the Median is the Mean of the middle two members.

1 {5, 1, 0, 3, 8} odd

First make sure the set is in order.

{0, 1, 3, 5, 8}

2 {6, 2, 7, 1} even

First make sure the set is in order.

{1, 2, 6, 7}

Then choose the middle member.

The Median is the Mean of the middle two.

Median = 2 + 6 = 4 2

3 {12, 9, 10}

4 {6, 1, 10, 7, 4, 2}

5 {1, 2, 3, 4, 5, 6, 7}

6 {1, 2, 3, 4, 5, 6}

7 {4, 0, 2, 0, 2, 1, 3}

8 {0, 1, 2, 2, 5, 8}

Finding the Mode

MMM 5

Instructions: Find the Mode of each set below. Remember, there may not be a Mode, or there may be more than one Mode. (Note: You can re-order the sets to make finding the Mode easier.)

1 {5, 2, 1, 5, 7, 3, 4, 6}

{1, 2, 3, 4, 5, 5, 6, 7}

2 {8, 0, 0, 2, 4, 8, 10}

{ 0, 0, 2, 4, 8, 8, 10}

The Mode is 5 because it is repeated most often.

3 {5, 1, 2, 5, 1, 5, 5}

Both 0 and 8 are Modes

4 {15, 5, 30, 60, 25}

5 {0, 1, 5, 1, 8, 3, 3, 9}

6 {0, 0, 1, 1, 2, 2, 3, 3}

7 {12, 10, 15, 12, 18}

8 {7, 9, 7, 4, 4, 3, 3, 4}

9 {1, 0, 1, 0, 1, 0}

10 {0, 1, 2, 3, 3, 3, 4, 4, 4}
