What would use if there are no big gaps in the middle of the data?

Median
The number that appears most frequently in a set of numbers, there may be one, more than one, or none.
Mode
What would you do if the data have many repeated numbers?
Mode
Values that are much greater or mean less than the rest of the date
Extreme Values
Outlier: __________ __________ in a _______ of numbers; a _________ that is ________ _________ or _______ _______ than the other __________.
Extreme values, set, value, much larger, much smaller, numbers
When would you use mode?
If the data have many repeated numbers.
The sum of a set of numbers divided by a number of elements in the set, often referred to as average.
Mean
What would you use when the data have no extreme values (values that are much greater or mean less than the rest of the data?
Mean
What are the measures of central tendency?
Mean, Median, and Mode
The middle of a set of numbers when the numbers are arranged in order from least to greatest; if there is an odd number of terms it is the middle term; if there is an even number of terms, it is the mean (average) of the two middle terms.
Median
Extreme values in a set of numbers; a number that is much larger or much smaller than the other number.
Outlier
The difference between the greatest and least values in a set of data.
Range
When would you use Median?
The data have extreme values. There are no big gaps in the middle of the data.
When is mean the most useful?
When the data have no extreme values (values that are much greater or mean less than the rest of the date.
Median: The ________ of a set of numbers when the numbers are ___________ in order from ________ to _______; if there is an ________ number of terms it is the _______ term; if there is an ________ number of terms, it is the _______ (average) of the ________ _______ terms.
