Data

Data values that are far away from most of the other data in a set...

• Gaps

• Outliers

• Averages

• Clusters

What is the most appropriate measure of variability to use when the mean is the best measure of center?

• interquartile range

• range

• mean absolute deviation

• mode

This consists of the minimum, the three quartiles, and the maximum. It is often indicated by a box plot.

• five-number summary

• statistical question

• data

• geogebra

Which class was more consistent in their Algebra Scores?

• Class #2
• Class #1
• Both classes had the same consistency.
• 50%

A distribution where one side of the distribution has more values farther from the bulk of the data than the other side, so that the mean is not equal to the median.

If our data is Symmetrical, which Measure of Variability should we use?

• IQR

• Standard deviation

• Mean

• Median

A distribution whose dot plot or histogram takes the form of a bell with most of the data clustered near the center and fewer points farther from the center.

How does the outlier in the data set below effect the mean?

• it increases the mean

• it decreases the mean

• it has no effect on the mean

• there is no outlier

What is the most appropriate measure of variability to use when the median is the best measure of center?

• range

• mean absolute deviation

• interquartile range

• spread

Which class has the higher test score median? 

• Class #1
• Class # 2 
• The medians are equal
• The median is not shown here.
