6th Period Histograms

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

How does a histogram differ from a bar graph?

Back

A histogram displays numerical data and shows the frequency of data within intervals, while a bar graph displays categorical data.

Front

What is the purpose of intervals in a histogram?

Back

Intervals group data points into ranges, allowing for a clearer visualization of the distribution of data.

Front

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

Back

The height of a bar represents the frequency or count of data points that fall within the corresponding interval.

Front

How can you determine the interval with the greatest frequency in a histogram?

Back

By comparing the heights of the bars, the interval with the tallest bar has the greatest frequency.

Front

What is the significance of the x-axis in a histogram?

Back

The x-axis represents the intervals or ranges of data values.

Front

What does the y-axis represent in a histogram?

Back

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

Front

How do you interpret a histogram with a uniform distribution?

Back

A uniform distribution histogram shows bars of approximately equal height, indicating that data points are evenly distributed across intervals.

Front

What does a skewed histogram indicate about the data?

Back

A skewed histogram indicates that the data is not evenly distributed, with a tail on one side showing that more data points fall on one end.

Front

What is the role of the total number of data points in a histogram?

Back

The total number of data points helps to understand the overall distribution and can be used to calculate relative frequencies.
