Document Summary
A table that organized your data by number of times different values occur, fully preserving the content of raw data. Step 1: determine highest and lowest score. Step 2: create 2 columns; label first with variable name and label second. Step 3: list full range of values that encompasses all the scores in the data set, from highest to lowest. Include all values in range, even for which frequency is zero. Step 4: count the number of scores for each value, and write those numbers in the frequency column. Example: how frequently a particular number is present. (there are 3 times that 52 is in the set, 4 times that 38 is in the set, etc. ) A visual depiction of data that reports frequencies within a given interval rather than the frequencies for a specific value. This can be very useful when we have many possible values for a variable: step 1.
