What are the disadvantages of frequency distribution tables
rang
According to Anderson, Sweeney Williams book Essential of Statistics For Business and Economics, 4e Edition, 2006 p. 34 cumulative frequency distribution is "a variation of the frequency distribution that provides another tabular summary of quantitative data." In simple terms, the cumulative frequency distribution is the sum of the frequencies of all points or outcomes below and including the current point.
It is derived frequency distribution. XD
The advantage of a grouped frequency distribution is that it is small enough for you to get a pretty good idea at a glance how the scores are distributed. The disadvantage is that you are lumping scores together, thus losing some of the information in the original scores.
A frequency distribution lists each value in the distribution and the number times it appears, while a relative frequency distribution reports the proportion of cases reporting each value
Advantages 1. C.F curves can be use to read off values both way round 2. The original information from a grouped frequency distribution can be onbtained from the C.F curves I dunno any disadvantages!!
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.

Cumulative Frequency is The total of a frequency and all frequencies so far in a frequency distribution. It is the 'running total' of frequencies in the frequency distribution table.

frequency distribution contain qualitative data
in form of percent
Are you talking about a histogram of the relative frequency distribution.
advantages: -very informative when examining how values are changing within the data set. -shows the running total of frequencies from the lowest interval up. disadvantages: -difficult to compare the frequencies between each data group. by Mr. Hsia
The frequency distribution table lists all the possible events and how many times (frequency) they occurred.
