Data Analysis-Dot Plot

Front

What is a dot plot?

Back

A dot plot is a simple way to display data using dots above a number line, where each dot represents one data point.

Front

How do you read a dot plot?

Back

To read a dot plot, count the number of dots above each value on the number line to determine how many times that value occurs.

Front

What does it mean if a dot plot has a high peak?

Back

A high peak in a dot plot indicates that a particular value occurs frequently in the data set.

Front

What is the purpose of using a dot plot?

Back

The purpose of using a dot plot is to visualize the distribution of data points and to easily identify trends, clusters, and gaps.

Front

How can you find the mode using a dot plot?

Back

The mode is the value that appears most frequently in the dot plot, represented by the highest peak.

Front

What is the median in a data set?

Back

The median is the middle value when the data points are arranged in order. If there is an even number of data points, it is the average of the two middle values.

Front

How do you determine the range of a data set from a dot plot?

Back

The range is found by subtracting the smallest value from the largest value in the data set.

Front

What does it mean if a dot plot is symmetrical?

Back

A symmetrical dot plot indicates that the data is evenly distributed around the center value.

Front

How can you identify outliers in a dot plot?

Back

Outliers are data points that are significantly higher or lower than the rest of the data, often appearing as isolated dots far from the main cluster.

Front

What is a frequency in the context of a dot plot?

Back

Frequency refers to the number of times a particular value appears in the data set, represented by the number of dots above that value.
