What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted on a number line, representing the frequency of data points.

How do you calculate the range of a data set?

Back

The range is calculated by subtracting the minimum value from the maximum value in the data set.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, using bars to show the frequency of data points within specified intervals.

Front

What is the mean of a data set?

Back

The mean is the average of a set of numbers, calculated by dividing the sum of all values by the number of values.

Front

How do you find the median of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle values.

Front

What is a box plot?

Back

A box plot is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) represents the range of the middle 50% of the data, calculated as Q3 - Q1.

Front

How do you interpret a histogram?

Back

In a histogram, the height of each bar indicates the frequency of data points within each interval, allowing you to see the distribution of the data.

Front

What is the purpose of a box plot?

Back

A box plot visually summarizes the distribution of a data set, highlighting the median, quartiles, and potential outliers.

Front

How do you find the mode of a data set?

Back

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