1. What is a frequency distribution?
A table or chart showing how often each value occurs in a dataset.
2. What is a frequency table?
A table that lists categories/values alongside the number of times (frequency) they
appear.
3. What does each column in a frequency table represent?
One column shows the category (or value), and the other shows its frequency.
4. What is absolute frequency?
The raw count of how many times a value occurs.
,5. Which frequency type answers: “How many students out of the total scored a letter
grade?”
Relative frequency.
6. What is relative frequency?
The proportion of observations in a category compared to the total frequency.
7. Formula for relative frequency?
Frequency in category ÷ total frequency.
8. Which frequency type answers: “How many students scored a B or better?”
Cumulative frequency.
9. What is cumulative frequency?
The sum of frequencies of a given category and all categories before it.
10. What kinds of variables can frequency tables be used for?
Qualitative or quantitative variables.
11. What are “bins” in frequency tables?
Groups into which quantitative data are divided for analysis.
12. What are frequency graphs?
Graphical displays of data such as pie charts, bar charts, histograms, polygons, and
stem-and-leaf plots.
13. Which graphs are used for qualitative variables?
Pie charts and bar charts.
, 14. Which graphs are used for quantitative variables?
Histograms, frequency polygons, and stem-and-leaf plots.
15. What do pie charts display?
Relative frequencies of categories, shown as slices of a circle.
16. What does each slice of a pie chart represent?
A category.
17. The size of each pie slice is proportional to…
The relative frequency of that category.
18. The entire pie chart represents…
100% of the dataset.
19. Pie charts are best for…
Showing frequencies with a small number of categories.
20. What do bar charts show?
Absolute or relative frequencies of qualitative data using bars.
21. In a bar chart, each bar represents…
A category.
22. The height of each bar represents…
The frequency of that category.
