What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data. Each bar represents an interval of values.

Front

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

Back

The height of a bar in a histogram represents the number of data points (frequency) that fall within the interval represented by that bar.

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 example, an interval of 10-14 includes all data points from 10 to 14.

Front

How do you determine the total number of data points in a histogram?

Back

To determine the total number of data points, add the heights of all the bars in the histogram.

Front

What is the purpose of a histogram?

Back

The purpose of a histogram is to visually represent the distribution of data, making it easier to see patterns, trends, and outliers.

Front

How can you find the mode using a histogram?

Back

The mode is the interval with the highest bar (tallest bar) in the histogram, indicating the most frequently occurring data range.

Front

What does it mean if a histogram is skewed to the right?

Back

If a histogram is skewed to the right, it means that there are more data points on the lower end of the scale, with fewer higher values.

Front

What does it mean if a histogram is symmetric?

Back

A symmetric histogram has a balanced shape, indicating that data points are evenly distributed around the center.

Front

How do you read the x-axis of a histogram?

Back

The x-axis of a histogram represents the intervals or ranges of values for the data being analyzed.

Front

How do you read the y-axis of a histogram?

Back

The y-axis of a histogram represents the frequency or count of data points within each interval.
