Instructions:
  • Answer 11 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The mode of a set of numbers is the number in the set that occurs most often. 1. If there is no number that occurs most often - the set has no mode. 2. If several numbers occur an equal number of times - the data set will have several modes.






2. The median of a set of numbers is the middle number when the numbers are arranged in ascending (or descending) order and there is an odd number of items. If there is an even number of items - the median is the average of the two middle numbers.






3. The number in a set that occurs most often. If no such number exists - there is no mode. - the most frequent value of a random variable






4. The mean (average) of a set of n numbers is the sum of the numbers divided by the number n of elements in the set.






5. The weighted mean of a set of n numbers is the sum of the products formed by multiplying each number by its assigned weight divided by the sum of all the weights. - the average of two means - calculated so that each mean is weighted by the number of






6. The median of a set of numbers is the middle number when the numbers are arranged in ascending order.






7. The mean of a set of n numbers is the sum of the numbers divided by n.






8. A type of graph that uses symbols to represent numerical data - A method of displaying data that involves using pictures to represent the data being counted.






9. A type of graph that usually shows a trend or change over time. The line graph shows the satisfaction or dissatisfaction of Americans with health care costs. - A graph that uses line segments to show changes that occur over time






10. A graph used to compare different categories by using bars whose lengths are proportional to the number of items in the category. The graph shows that most adults want to live to be 100. - a type of graph in which the lengths of bars are used to repr






11. A type of graph that shows what percent of a quantity is used in different categories or the ratio of one category to another - A graph that uses sectors of a circle to compare parts to the whole and parts to other parts.
