Understanding Dot Plots, Box Plots, and Histograms

What does a box plot display?

• Frequency of data as bars

• Minimum, maximum, and median of a dataset

• Each data value as a dot

• Data values in sequential order

What is the median in a dataset?

• The middle value when data is ordered

• The difference between the highest and lowest values

• The average of all data points

• The most frequent value

How is the interquartile range calculated in a box plot?

• Maximum minus minimum

• Upper median minus lower median

• Median minus minimum

• Maximum minus median

What is the purpose of the lower and upper medians in a box plot?

• To calculate the range of the dataset

• To indicate the start and end of the box

• To divide the dataset into halves

• To show the minimum and maximum values

How do you find the interquartile range from a given box plot?

• Calculate the average of all quartiles

• Find the difference between the median and the minimum

• Add the minimum and maximum values

• Subtract the lower quartile from the upper quartile

What represents the frequency of data in a dot plot?

• The length of bars

• The distance between dots

• The number of dots at each point

• The color of dots

How do histograms differ from dot plots?

• Histograms use lines instead of dots

• Histograms show data frequency as bars

• Dot plots can't show large datasets

• Dot plots use bars to show frequency

What is the first step in creating a dot plot?

• Identifying minimum and maximum values

• Drawing the number line

• Finding the median

• Placing the dots

In a histogram, what does the height of a bar represent?

• The median of the dataset

• The range of the dataset

• The frequency of data values

• The total number of data points

Which graph is best for showing the distribution of a dataset?

• Histogram

• All of the above

• Box plot

• Dot plot
