1What term refers not only to a table that reports the number of observations that fall into each category of a variable but also the first step in statistical analysis?
Frequency Distribution
2What symbol denotes the frequency of a given category?
f
3What term tefers to the frequency of a category divided by the total number of cases?
Proportion
4What symbol denotes proportion? What’s the formula?
p = f/N
5What symbol denotes the total cases? What must proportions add up to?
N; 1.00
6What term refers to the proportion multiplied by 100?
Percentage
7Which level of measurement involves counting frequencies and reporting percentages with no ranking?
Nominal
8Which level of measurement involves counting and ranking, with categories listed in order?
Ordinal
9Which level of measurement involves counting, ranking, and comparison of exact differences (often grouped into intervals)?
Interval-ratio
10What kind of table collapses individual values into class intervals of equal width?
Grouped frequency distributions
11What kind of distribution shows frequencies at or below each category? (Ordinal/Interval-ratio only)
Cumulative Frequency (Cf)
12What kind of distribution shows the percentage at or below each category?
Cumulative percentage (C%)
13What can be obtained by dividing the number of frequencies by the population?
Rate
14How are rates expressed?
In 1000s
15What kind of rate uses the total population as a denominator?
Crude Rate
16What kind of graph shows the difference in frequencies/percentages among categories of nominal/ordinal variables as segments of a circle that sum to 100%? (6 or fewer categories)
Pie Chart
17What kind of graph shows differences in frequencies/percentages among nominal/ordinal categorical varianles, displayed as equal width rectangles with space between?
Bar Graph
18What kind of graph shows differences in frequencies/percentages among interval-ratio/ordinal variables with touching bars whose width is proportional to the width of the interval, the height to the frequency?
Histogram
19What kind of graph presenta geographical data variation patterns across geographic units like census data?
Statistical Map
20What kind of graph shows differences in frequencies/percentages among categories of interval-ratio variables with points placed above each category?
Line Graph
21What kind of graph shows changes in a variable at different points in time?
Time-Series Chart
