Chapter 2: frequency distribution: frequency distributions, raw scores. Data point that has not yet been transformed or analyzed: frequency table. Visual depiction of data that shows how often each vale occurred. Create two columns; label first with variable name; label second frequency . List full range of values that encompass all the scores in the data set, from highest to lowest. Count number of scores at each value, and write those numbers in each frequency column: grouped frequency table. Visual depiction of data that reports frequencies within a given interval rather than the frequencies for specific value. Find highest and lowest scores in frequency distribution. Determine number of intervals and best interval size. Figure out number that will be he bottom of lowest interval. Finish table by listing intervals from highest to lowest and then counting numbers of scores in each: histograms.
