Double Box Plots

Front

What is a double box plot?

Back

A double box plot is a graphical representation that displays the distribution of two sets of data side by side, allowing for easy comparison of their medians, quartiles, and overall spread.

Front

What does the box in a box plot represent?

Back

The box in a box plot represents the interquartile range (IQR), which contains the middle 50% of the data, extending from the first quartile (Q1) to the third quartile (Q3).

Front

What do the whiskers in a box plot indicate?

Back

The whiskers in a box plot extend from the box to the smallest and largest values within 1.5 times the interquartile range (IQR) from the quartiles, showing the range of the data.

Front

How do you find the median from a box plot?

Back

The median is represented by a line inside the box of the box plot, dividing the box into two parts.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the central tendency, variability, and distribution of a dataset.

Front

What does a longer box in a box plot indicate?

Back

A longer box in a box plot indicates greater variability or spread in the data.

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), representing the range of the middle 50% of the data.

Front

How can you determine which data set has a greater spread using box plots?

Back

You can determine which data set has a greater spread by comparing the lengths of the boxes and the whiskers in the box plots.

Front

What does it mean if the median of one data set is higher than another in a box plot?

Back

If the median of one data set is higher than another in a box plot, it indicates that the central tendency of that data set is greater.

Front

What is a quartile?

Back

A quartile is a type of quantile that divides a dataset into four equal parts, with each part representing 25% of the data.
