Algebra - Statistics Test Review

What % of the data is less than 14?

• 25% because it is one section of the boxplot.

• 50% because it is two sections of the boxplot.

• 75% because it is three sections of the boxplot.

• 100% because it is the entire the boxplot.

Is the best estimate of the mean 14.8, 15, or 16.8??

• 15 because the mean is likely the same as the median.

• 14.8 because the mean is likely less than the median.

• 16.8 because the mean is likely greater than the median.

The data set {20, 54, 55, 62, 63, 67, 70, 75, 80} has a min: 20, Q1: 54.5, med: 63, Q3: 72.5, and max: 80.

What is the upper fence value?

Mathematical Equivalence

ON

The data set {20, 54, 55, 62, 63, 67, 70, 75, 80} has a lower fence value of 27.5 and an upper fence value of 99.5.

Are there any outliers?

• There are no outliers because all data falls between the LF and UF values.

• 20 is an outliers because it below the lower fence value.

• 80 is an outlier because it above the upper fence value.

The data set {4, 5, 6, 6, 8, 10, 12} has a 5-number summary of min: 4, Q1: 5, Q2: 6, Q3:10, and max: 12.

Which boxplot represents the data?
