What is a cumulative frequency distribution?
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.
How many advantages and disadvantages of cumulative frequency?
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!!
What is derived frequency distribution?
It is derived frequency distribution. XD
What is the difference of frequency distribution and relative frequency distribution?
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
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
What is mean of term of frequency density?
Frequency density refers to the number of data points within a certain interval or range in a dataset. It is calculated by dividing the frequency of data points in a particular interval by the width of that interval. This measure helps to visualize and compare the distribution of data in a histogram or frequency distribution chart.
How is a frequency curve in statistics different from a frequency polygon?
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.

What are advantages and disadvantages of cumulative frequency?
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

What is the cumulative column frequency distribution table?
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.
Is a frequency polygon plotted in the middle?
Yes, a frequency polygon is typically plotted by connecting points that represent the midpoints of each class interval in a frequency distribution. The points are plotted above the midpoints, with the frequency on the vertical axis and the class intervals on the horizontal axis. This visualization helps to show the shape of the distribution of the data. The polygon is often closed by connecting the endpoints to the horizontal axis at the minimum and maximum class intervals.
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
What is the frequency of the monthly coupon distribution?
The frequency of the monthly coupon distribution is once a month.
What kind of chart uses rectangles to show frequency distribution?
A histogram uses rectangles to represent the frequency distribution of a dataset. In a histogram, the width of each rectangle corresponds to the interval of values (bins), while the height indicates the frequency of data points within that interval. This visual representation helps to identify patterns, such as the shape of the distribution, central tendencies, and variability within the data.
