Here are some statistical data and questions about the population of the fifty states and DC. Study them and determine how difficult would it be to answer the questions using the dot plot.
Every ten years, the United States conducts a census, which is an effort to count the entire population. The dot plot shows the population data from the 2010 census for each of the fifty states and the District of Columbia (DC).
Here below are the population data for all states and the District of Columbia from the 2010 census.
Here is a histogram that shows the weight of some dogs in pounds.
Each bar includes the left-end value but not the right-end value. For example, the first bar includes dogs that weigh 60 pounds and 68 pounds but not 80 pounds.
(1.) How many dogs weigh at least 100 pounds?
(2.) How many dogs weigh at least 70 pounds?
(3.) How many dogs weigh at least 120 pounds and less than 160 pounds?
(4.) How much does the heaviest dog at the show weigh?
(5.) What would you consider a typical weight for a dog at this dog show? Explain your reasoning.
(6.) If you used the dot plot to answer the same five questions you just answered, how would your answers be different?
(7.) How are the histogram and the dot plot alike? How are they different?
Construct a Histogram.
Match histograms A through E to dot plots 1 through 5 so that each match represents the same data set.
This table shows the times, in minutes, it took 40 sixth-grade students to run 1 mile. Draw a histogram for the information in the table.
Here is a histogram that summarizes the lengths, in feet, of a group of adult female sharks.
