Front

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.

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 within specified intervals.

Front

How do you determine the mode from a dot plot?

Back

The mode is the value that appears most frequently in the dot plot.

Front

What does the height of a bar in a histogram represent?

Back

The height of a bar in a histogram represents the frequency of data points within that interval.

Front

How can you find the range of a data set?

Back

The range is found by subtracting the smallest value from the largest value in the data set.

Front

What is the mean of a data set?

Back

The mean is the average of all data points, calculated by dividing the sum of the values by the number of values.

Front

What is the purpose of using a histogram?

Back

A histogram is used to visualize the distribution of data and to identify patterns, trends, or outliers.

Front

How do you read a dot plot?

Back

To read a dot plot, count the number of dots above each value on the number line to determine the frequency of each value.

Front

What is an interval in a histogram?

Back

An interval in a histogram is a range of values that groups data points together for frequency representation.

Front

How do you identify the greatest frequency in a histogram?

Back

The greatest frequency is identified by finding the tallest bar in the histogram.
