What is the sum of proportions computed from a frequency distribution have to equal?
The sum of proportions computed from a frequency distribution must equal
What are modes of distribution?
The data values with the highest frequency, gives the peak of the distribution graph.
What is an 'ungrouped frequency table'?
A frequency distribution of numerical data where the raw data is not grouped.
Does a simple frequency distribution provides the frequency of responses for each class interval?
Yes.
What is used to display data from frequency distribution?

What graphs are used in frequency distribution?

What are frequency Polygon?
Frequency polygons are graphical devices used for understanding the shapes of distribution.
What is derived frequency distribution?

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
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.
What table is used to group data into intervals?

What are the disadvantages of frequency distribution in points?
What are the disadvantages of frequency distribution tables
A grouped frequency distribution is used when the range of data values is relatively small. True or false?
False. When the range is large you would use a grouped frequency distribution.
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
What is 2k rule?
The 2k or 2 to K rule is used to determine the number of classes for a frequency distribution. The 2k rule should be used as a guide more than a dictator of determining the number of classes for a frequency distribution.
Is the cummulative frequency distribution a relative frequency distribution expressed in absolute numbers?
in form of percent
