The fx column in a Frequency Distribution Table is the frequency (f) multiplied by the Class Centre or score (x). If the score is 22. And the freqency for that score is 7. fx = 22*7 = 154 You can use the total of the fx column to find the mean. The total fx divided by the total frequency = Mean.

look at this site - the info on how to find frequency, relative & relative cumulative frequency is very clear and easy to understand :) http://cnx.org/content/m16012/latest/ look at this site - the info on how to find frequency, relative & relative cumulative frequency is very clear and easy to understand :) http://cnx.org/content/m16012/latest/

The answer depends on what information you do have.

find the frequency before finding the percent total -_- :)

find the mean in a set of frequency distribution

A Gaussian distribution has the mean at the highest value. Sum all the values and divide by the number of values. * * * * * A very partial answer and one that does not address the question which was in the context of a frequency distribution table. If the frequencies are for grouped data, replace the range of each group by its midpoint. This, then, comprises the set of values, x, for the random variable. For each x there is an associated frequency, f. Multiply each x by its frequency and add these together. Divide the answer by the sum of the f values. That is the mean.

A frequency table is not something that one can purchase. This is a mathematical table that is used for statistics. One can find much more detail about frequency tables on the Wikipedia website.

Range = Maximum value - Minimum value

it is used to find mean<median and mode of grouped data

You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.

The best time to use a frequency table is when you have disorganized raw data, that need to be sorted, usually to find trends in the data.
