What else can I help you with?
Which of these is best used for displaying frequency distributions when one or two categories make up a large proportion of the total?
The answer depends on what is meant by two or more. If it refers to around 4 to 7 then a pie chart may be best: it depends on whether it is appropriate to lump all the remaining categories as an "other" category.If there are 6 or more categories then a bar chart may be appropriate but again, that depends on whether lumping the remainder together as an "other" category makes sense.
What table lists the categories of a variable and gives the proportion of observation for each category?
A frequency table. Learn to read your Statistics book next time.
Why are open-ended frequency distributions necessary?
to quickly and effectively represent data
What are advantages and disadvantages of frequency polygon?
A frequency polygon is not very effective in displaying group data when the class sizes are not the same.
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.

What is a frequency distributions?
The frequency distribution shows in a graph or a table all the possible values of a variable, called the random variable, and the frequency or the count of each value. For example, if you had the ages of 100 people you could do a frequency distribution and split the ages into 10 year categories and then show how many of the 100 people were in the 20s, how many in their 30s, how many in their 40s and so on.
Can frequency distributions contain more than ten observations?
Yes.
What are three types of frequency distributions?
1) Ungrouped2) Grouped 3) Qualitative
Why are open-ended frequency distributions necessary?
to quickly and effectively represent data
What are advantages and disadvantages of frequency polygon?
A frequency polygon is not very effective in displaying group data when the class sizes are not the same.
Could a frequency table count the number of times a certain piece of information appears in a data set?
Yes, a frequency table can count the number of times a specific piece of information appears in a data set. It organizes data into categories and displays the frequency of each category, allowing for easy identification of how often each value occurs. This makes it a useful tool for summarizing and analyzing data distributions.
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
What is the sum of proportion compted from a frequency distribution must equal?
1
What are some benefits of representing data sets using frequency distributions?
Organizing the data into a frequency distribution can make patterns within the data more evident.
What is a graph used to compare categories of data?
frequency table
