What is the MEAN?How do we find it?

The mean is the numerical average of the data set.

The mean is found by adding all the values in the set, then dividing the sum by the number of values.

Lets find Abby’s MEAN science test

score?

9784

97

95

86+

783

783 ÷ 9

The mean is 87

What is the MEDIAN?How do we find it?

The MEDIAN is the number that is in the middle of a set of data

1. Arrange the numbers in the set in order from least to greatest.

2. Then find the number that is in the middle.

Page 9: What is the MEAN? How do we find it? The mean is the numerical average of the data set. The mean is found by adding all the values in the set, then.

978473 88 10063 979586

The median is 88.

Half the numbers are

less than the median. Half the numbers are

greater than the median.

Page 10: What is the MEAN? How do we find it? The mean is the numerical average of the data set. The mean is found by adding all the values in the set, then.

MedianSounds like MEDIUM

Think middle when you hear median.

Page 11: What is the MEAN? How do we find it? The mean is the numerical average of the data set. The mean is found by adding all the values in the set, then.

How do we findthe MEDIAN

when two numbers are in the middle?

1. Add the two numbers.

2. Then divide by 2.

Page 12: What is the MEAN? How do we find it? The mean is the numerical average of the data set. The mean is found by adding all the values in the set, then.

978473 88 10063 9795

88 + 95 = 183

183 ÷ 2 The median is91.5

What is the MODE?How do we find it?

The MODE is the piece of data that occurs most frequently in the data set.

A set of data can have:

One mode More than one mode No mode

Page 16: What is the MEAN? How do we find it? The mean is the numerical average of the data set. The mean is found by adding all the values in the set, then.

978473 88 10063 979586

The value 97 appears twice.All other numbers appear just once.

97 is the MODE

A Hint for remembering the MODE…

The first two letters give you a hint… MOde

A box plot summarizes data using the median, upper and

lower quartiles, and the extreme (least and greatest) values. It allows you to see important characteristics of

the data at a glance.
