What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, where the data is divided into intervals (bins) and the frequency of data points in each interval is represented by the height of the bars.

How do you determine the mode from a dot plot?

Back

The mode is the value that appears most frequently in the dot plot, represented by the column with the most dots.

How do you read the intervals in a histogram?

Back

Intervals in a histogram are the ranges of values that data points fall into, and each interval is represented by a bar whose height indicates the frequency of data points within that range.

What is the difference between a dot plot and a histogram?

Back

A dot plot displays individual data points as dots along a number line, while a histogram groups data into intervals and displays the frequency of data points in those intervals as bars.

How can you find the median from a dot plot?

Back

To find the median from a dot plot, you must first order the data points and then locate the middle value. If there is an even number of data points, the median is the average of the two middle values.

What is an outlier in a data set?

Back

An outlier is a data point that is significantly different from the other data points in the set, often lying outside the overall pattern of distribution.

Front

How can you identify the range of a data set using a histogram?

Back

The range of a data set can be identified by subtracting the smallest value from the largest value represented in the histogram.
