Document Summary

Can see the entire set of scores at a glance. Can be structured as a table or a graph. Both have the same two elemtns: a set of categories that make up the original measurement scale, a record of the frequency. How to make a frequency distribution table: arrange the possible x values from highest to lowest a. Including x values with 0 frequency: for nominal scales categories can be in any order. List the frequency of each value in the data set: the sum of this column f should add up to sample size. Proportion (p) measures the fraction of the total group that is associated with each score. Used when a data set has a wide range of values. Group scores into intervals and then list the interval on the table. Percentage of individuals in the distribution with scores at or below the particular value.
