Creating and Analyzing Dot Plots

What is the primary purpose of using a dot plot in statistics?

• To predict future trends

• To perform complex calculations

• To display frequency and distribution of data

• To calculate the mean of data

What does the frequency of a data value indicate in a dot plot?

• How often that value occurs

• The middle value of the data

• The total sum of all data points

• The average value of the data

How many pets do most of the friends own according to the dot plot?

• Zero to two pets

• None of the friends own pets

• Three to five pets

• More than five pets

According to the dot plot, how many friends own exactly one pet?

• Five friends

• Six friends

• Three friends

• Four friends

What is the range of the number line used in the dot plot for the 50 meters run?

• 1 to 10

• 9 to 15

• 5 to 20

• 10 to 20

How many students ran faster than 12 seconds?

• Five students

• Twelve students

• Seven students

• Ten students

Which data value has the greatest frequency in the dot plot for the 50 meters run?

• 10 seconds

• 9 seconds

• 15 seconds

• 12 seconds

How many students were timed in the 50 meters run?

• 11 students

• 10 students

• 13 students

• 12 students

What is a key similarity between dot plots and box plots?

• Both predict future data trends

• Both use a number line to show data distribution

• Both are used exclusively for time-series data

• Both show every individual data value

What is a major difference between dot plots and box plots?

• Box plots use a number line, dot plots do not

• Dot plots use a number line, box plots do not

• Box plots show every data value, dot plots do not

• Dot plots show every data value, box plots do not
