Compare Dot Plots

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of data points plotted on a simple scale, typically using dots to represent the frequency of values.

Front

How do you find the median of a data set?

Back

To find the median, arrange the data points in numerical order and identify the middle value. If there is an even number of values, the median is the average of the two middle values.

Front

What does it mean for a data set to have a higher median?

Back

A higher median indicates that the middle value of the data set is greater compared to another data set, suggesting that the overall values are larger.

Front

What is spread in statistics?

Back

Spread refers to how much the data values vary or differ from each other, often measured by range, interquartile range, or standard deviation.

Front

What is an outlier?

Back

An outlier is a data point that is significantly different from the other data points in a set, often lying far away from the rest of the values.

Front

What does it mean for data to be symmetric?

Back

Data is symmetric if the left and right sides of the distribution are mirror images of each other, indicating that the mean and median are equal.

Front

How do you compare the centers of two data sets?

Back

To compare the centers, look at the median or mean of each data set to determine which one is higher or lower.

Front

What is the difference between the medians of two data sets?

Back

The difference between the medians is calculated by subtracting the median of one data set from the median of the other.

Front

What is the range of a data set?

Back

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

Front

How can you identify an outlier in a dot plot?

Back

An outlier can be identified in a dot plot as a point that is far removed from the cluster of other points.
