Envision Topic 8 Review Part 1

Front

What is a Box & Whisker plot?

Back

A Box & Whisker plot is a graphical representation of data that shows the distribution of a dataset based on five summary statistics: minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the smallest value in the dataset from the largest value.

Front

What does the median represent in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. It divides the dataset into two equal halves.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3) and represents the range of the middle 50% of the data.

Front

What percentage of data lies below the median in a Box & Whisker plot?

Back

50% of the data lies below the median in a Box & Whisker plot.

Front

How can you determine which Box & Whisker plot has the highest median?

Back

The Box & Whisker plot with the highest line in the middle (the median line) represents the highest median.

Front

What does it mean if a Box & Whisker plot has a long whisker on one side?

Back

A long whisker on one side indicates a larger spread of data on that side, suggesting more variability in the values.

Front

If 25% of the data is above a certain value in a Box & Whisker plot, what does this indicate?

Back

This indicates that the value is greater than 75% of the data points in the dataset.

Front

What is the significance of the quartiles in a Box & Whisker plot?

Back

Quartiles divide the dataset into four equal parts, helping to understand the distribution and spread of the data.

Front

How do you interpret the range of test scores for two students?

Back

To compare the range of test scores, calculate the range for each student and determine which range is larger.
