Histogram Flashcard

A histogram is a type of bar graph that represents the frequency distribution of numerical data. It shows how many data points fall within certain ranges (bins).

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

The y-axis represents the frequency or count of data points that fall within each bin.

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

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

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

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

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

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

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