Dot Plots - 7 Staar

A dot plot is a statistical chart that uses dots to represent the frequency of data points in a dataset.

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

IQR stands for Interquartile Range, which measures the spread of the middle 50% of data.

IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).

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

It means that the middle value of both datasets is the same, indicating similar central tendencies.

An outlier can be identified as a point that lies far away from the rest of the data points.

Dot plots are used to visualize the distribution of data and to easily identify trends, medians, and outliers.

The range is the difference between the highest and lowest values in a dataset.

To find the range, subtract the smallest value from the largest value in the dataset.
