  1. 2. The mean is this. Isn't always accurate but can help find the answer.
  2. 4. Values that divide a data set into quarters. Synonymous with IQR.
  3. 8. Measure of how spread out a data set is.Shows how big a set of data is.
  4. 11. Results of other charts/graphs. Listed numbers that show results
  5. 12. multiple modes in a data set.Usually found in larger sets of data.
  6. 13. Average of all the values in the population
  7. 15. Is the arithmetic average of a set of given numbers.It is calculated by taking all of the values in a set and dividing them by the total number of values in that set.
  8. 16. deviation Also called the standard error is the square root of the variance and tells us how spread out the data is from the mean.
  9. 18. Is the number that is in the middle of a data set that is organized from lowest to highest or from highest to lowest. Doesn’t represent a true average.
  10. 19. Numbers in a data set that are either way bigger or way smaller than the other numbers in a data set.Look different than the other numbers in the data set.
  11. 20. Is the number that repeats most often in a data set. Not a reliable measure of center.

  1. 1. Places each number in a data set into four percentages. Can show how big a data set is.
  2. 3. Average of all the values collected.
  3. 5. The order in which the data set goes. Synonymous with smallest going to largest.
  4. 6. Is calculated by adding the highest and lowest values of a data set together, and dividing the sum by 2. Hardly ever used.
  5. 7. Two modes in a data set.Usually found in medium sized sets of data.
  6. 9. One mode in a data set.Usually for smaller sets of data.
  7. 10. List of numbers in a data set. Usually going from least to greatest.
  8. 14. Measures the middles 50% of data. Separates the first and third quartiles.
  9. 17. The spread of each number. Used to show the difference in lowest to highest, synonymous with range.
