It is a mathematically calculated summary statistic. With discrete distributions it is the arithmetic mean whereas with a continuous distribution it is the value of the random variable (RV) such that it divides the area under the probability distribution curve in half.
A frequency distribution plot.
Are you talking about a histogram of the relative frequency distribution.
What are the importance of frequency
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
binominal distribution
It is derived frequency distribution. XD
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
It is the set of values that a variable can take together with the probability or frequency distribution for those values.
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.
find the mean in a set of frequency distribution
What are the disadvantages of frequency distribution tables
A histogram is "a representation of a frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportional to the corresponding frequencies.Broken distribution means that no data point falls in that class.
frequency distribution contain qualitative data
it is used to find mean<median and mode of grouped data
A frequency distribution plot.
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.
