Front

What is a dot plot?

Back

A dot plot is a simple visual representation of data where each data point is shown as a dot above a number line.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, where data is grouped into bins and the frequency of data points in each bin is represented by the height of bars.

Back

A box and whisker plot is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile, median, third quartile, and maximum.

Front

How do you find the maximum value in a data set?

Back

The maximum value is the largest number in the data set.

Front

How do you find the minimum value in a data set?

Back

The minimum value is the smallest number in the data set.

Front

What is the median of a data set?

Back

The median is the middle value when the data points are arranged in ascending order. If there are two middle numbers, add them together and divide by two.

Front

What does the term 'quartile' mean?

Back

A quartile is a type of quantile that divides a data set into four equal parts, with each part containing 25% of 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) and measures the spread of the middle 50% of the data.

Front

How do you interpret the median in a box and whisker plot?

Back

The median is represented by the line inside the box and indicates the middle value of the data set.

Front

What does the whisker represent in a box and whisker plot?

Back

The whiskers extend from the box to the smallest and largest values that are not outliers, showing the range of the data.
