Interpret: Mean, Median, Standard Dev., IQR

Which is the best interpretation of "mean"?

• Average

• About half the values are above and half are below

• Range of the middle half of values

• Middle

Which is the best interpretation of "median"?

• Average

• About half the values are above this value and about half are below

• Range of the middle half of values

• Typical distance from the mean

Which is the best interpretation of "median"?

• Average

• Middle

• Range of the middle half of values

• Typical distance from the mean

Which is the best interpretation of "standard deviation"?

• Typical distance from the median

• About half the values are above this value and about half are below

• Range of the middle half of values

• Typical distance from the mean

Which is the best interpretation of "interquartile range (IQR)"?

• Typical distance from the median

• About half the values are above this value and about half are below

• Range of the middle half of values

• Typical distance from the mean

Which is the best interpretation of "interquartile range (IQR)"?

• Typical distance from the median

• About half the values are above this value and about half are below

• Typical distance from the mean

• Distance from the 1st quartile to the 3rd quartile

For the data: 4,5,5,5,6,7,8,8,9,10

The only value that could logically be the mean would be:

• 4.1

• 6.7

• 9.5

• 12.3

For the data: 34,35,35,35,36,37,38,38,39,40

The only value that could logically be the median would be:

• 36.5

• 39

• 40.5

• 42

For the data: 34,35,35,35,36,37,38,38,39,40

If the mean is 36.7, the only value that could logically be the standard deviation would be:

• 36.5

• 2

• -3

• 20

For the data: 34,35,35,35,36,37,38,38,39,40

The only value that could logically be Q₁ would be:

• 34

• 35

• 39

• 40
