What does the x-axis represent in a histogram?

Back

The x-axis represents the intervals or bins of the data, showing the range of values.

Front

What does the y-axis represent in a histogram?

How do you determine the mode from a histogram?

Back

The mode is the bin with the highest bar, indicating the range with the most data points.

Front

What is the purpose of using a histogram?

Back

A histogram helps visualize the distribution of data, making it easier to identify patterns, trends, and outliers.

Front

What is the difference between a histogram and a bar graph?

Back

A histogram displays continuous data in intervals, while a bar graph displays categorical data.

Front

How can you find the total number of data points from a histogram?

Back

Add the heights of all the bars together to find the total frequency.

Front

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

Back

A right-skewed histogram indicates that most data points are concentrated on the left, with a few larger values on the right.

Front

What does it mean if a histogram is symmetric?

Back

A symmetric histogram indicates that the data is evenly distributed around the center.

Front

How do you interpret the height of a bar in a histogram?

Back

The height of a bar indicates the number of data points that fall within that specific range.
