Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, and maximum values.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the numbers in ascending order and identify the middle value. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the mean of a dataset?

Back

The mean is calculated by adding all the numbers in a dataset and dividing by the total number of values.

Front

What is the mode of a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

What does it mean if a box plot has a longer whisker on one side?

Back

A longer whisker indicates a greater spread of data on that side, suggesting more variability in the values.

Front

What is the interquartile range (IQR)?

Back

The 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

How do you interpret the median in a box plot?

Back

The median line in a box plot divides the dataset into two equal halves, indicating that 50% of the data points are below this value.

Front

What is the significance of the quartiles in a box plot?

Back

Quartiles divide the dataset into four equal parts, providing insights into the distribution and spread of the data.

Front

How can you determine the range of a dataset?

Back

The range is found by subtracting the minimum value from the maximum value in the dataset.

Front

What does it mean if two box plots have the same median?

Back

If two box plots have the same median, it indicates that the central tendency of the two datasets is similar, but it does not imply that the distributions are identical.
