30-39
When organizing data into frequency distributions, if the largest number is 99 and we are grouping by 10s, how many classes result from this grouping?
Seven classes
Using cutpoint grouping, if the first class width is defined as 120 under 140, what is the class width?
20
What should be subtracted from the lower limit and added to the upper limit when calculating class boundaries for a frequency distribution with a gap between class limits?

For class 30-39 in a frequency table, what would be the lower class limit?
30
When constructing a frequency table, what is the purpose of a tally table?
To count frequencies
If data are continuous and expressed with decimals, which method of grouping is particularly useful for organizing data into frequency distributions?
Cutpoint grouping
In exclusive series, how are the upper limits of one class and the lower limits of the next class treated?
Excluded in both classes
When using a class width of 20 and a first cutpoint of 120, what would be considered in the second class interval?
120-140
What is true about cumulative frequency distribution in relation to frequency distribution?
It displays total frequencies up to certain limits.
This quiz covers topics related to creating a cumulative frequency table and histogram from a given set of height data. Students will practice organizing the data into class intervals, calculating cumulative frequencies, and constructing a histogram based on the frequency distribution.
