Choosing the Best Graphs for Data Using Measures of Center

The video tutorial explains how to choose the best graph for data representation using measures of center such as median, mode, and range. It discusses the characteristics of dot plots, histograms, and box plots, and provides examples with different data sets, including student name lengths, bowling scores, and ages of children at a movie. The tutorial emphasizes the importance of understanding data characteristics to select the most appropriate graph for effective data visualization.

What is the median in a data set?

• The number that appears most frequently

• The difference between the highest and lowest values

• The number in the middle of an ordered data set

• The average of all numbers in the data set

Which graph is best for showing the mode of a data set?

• Box plot

• Line graph

• Dot plot

• Histogram

What does a histogram best highlight in a data set?

• Peaks within a range

• The exact mode

• The range

• The median

Why might a dot plot not be suitable for a data set with a large range?

• It does not show peaks

• It cannot display the mode

• It becomes cluttered and hard to read

• It cannot show the median

When is it appropriate to use all three types of graphs: histogram, dot plot, and box plot?

• When the data set has multiple modes

• When the data set has a large range

• When the data set has a small range

• When the data set has no mode
