Frequencies

1. Move the variables to the left box that you want to examine.
2. Click Statistics button
                Under Central Tendency you should select mean, and median
                If you are looking for percentiles you can use the percentiles box to find them.
                Under Dispersion, you should examine Standard Deviation, Range (the difference between the
                    Minimum value and the Maximum value), Minimum and Maximum.

3. The output will give you boxes for each of the variables you wanted to look at. The first is the statistics box which tells you:
        N- tells you the sample size; valid means data was entered there and missing means the data is missing
        Mean- is the mean
        Median- is the median
        Std Deviation- is the Standard Deviation.
        Range- the difference between the Minimum value and the Maximum value
        Minimum- is the lowest value entered
        Maximum- is the highest value

4. The next box is the Frequency Table, it shows you how many times each value occurred in order from lowest to highest.
        Valid- the column refers to the actual number entered into the data set, if you have data missing it will be listed at
                the bottom next to missing.
        Percent- is the percent that that value was entered in the data set
        Cumulative Percent- is the cumulative percent of the data values (the sum of all the values that are lower than and
                including the current one, it gives you percentiles.)
