Dot Plots & Histograms

A dot plot is a statistical chart that consists of dots plotted on a number line, representing the frequency of data points.

A histogram is a graphical representation of the distribution of numerical data, using bars to show the frequency of data within specified intervals.

The mode is the value that appears most frequently in the dot plot.

The height of a bar in a histogram represents the frequency of data points within that interval.

Dot plots are used to visualize small sets of data and to identify patterns, trends, and outliers.

To find the median, arrange the data points in order and identify the middle value.

A dot plot displays individual data points, while a histogram groups data into intervals and shows frequency.

Frequency refers to the number of times a particular value or range of values occurs in a dataset.

To create a histogram, divide the data into intervals (bins) and count how many data points fall into each interval.

An outlier is a data point that is significantly different from the other points in the dataset.
