Q

Tables that have textual data

A

Word/textual table

25
T/F: Word/textual table serve the same purpose as any table - comparison
T
26
Numerical table: A ratio of the number of observations in a statistical category to the total number of observations (proportion or %)
Relative frequency table
27
Numerical table: a table which presents proportion data and categorical variables
Relative frequency table
28
Relative frequency table: Presents data with respect categories of one variable only
One-way
29
Relative frequency table: data with respect to cross-classification of two categorical variables
Two-way
30
Relative frequency table: data with respect to more than two categorical variables
Multi-way
31
tables that can present data of a - descriptive statistics - inferential statistics
Statistical tables
32
to facilitate tabulation in the absence of a computer
Master table
33
shows the distribution of observations across several variables of interest in a given study
Master table
34
each observation is cross-classified across the variables
Master table
35
skeleton tables
Dummy tables
36
preview of tables to be
Dummy tables
37
Uses of dummy tables
.help researcher clarify instrument .help protocol reviewer .guides data analyst/programmers
38
Usual errors in table construction
1. comparison based on absolute numbers 2. use of wrong denominators in computing for percentages
39
visual representation of relationship between, but not restricted to, two variables
Graphical presentation
40
Instances where graph are not appropriate
* Data are very dispersed * Too few data (categories) * Numerous data * Data show little or no variation
41
Type of graph: Shows breakdown of a group or total where the no. of categories is not too many
Pie chart
42
Type of graph: Readily compares the percentages in each category by comparing the heights of the bars
Bar graph
43
Type of bar graph: Usually used for discrete quantitative variables
Vertical bar graph
44
Type of bar graph: Used for qualitative variables
Horizontal bar graph
45
Type of graph: A bar divided into smaller rectangles representing the parts
Component bar graph
46
T/F: A horizontal bar graph is similar to a pie chart
F (component bar graph)
47
___ is preferable over pie chart in situations where the compositions of two or more groups are to be compared
Component bar graph
48
Type of graph: Graphical representation of the frequency distribution of a continuous variable
Histogram
49
T/F: it is important to leave spaces between the bars of histogram to avoid confusion
F (no space between bars in an important characteristic of this graph)
50
In histogram, ___ may show the absolute or relative frequencies
Vertical scale
51
Type of graph: Plot of dots ( representing values of the variable) joined with lines over some period of time in sequential series
Line graph
52
Type of graph: Time series is shown along the horizontal axis while the variable values are shown along the vertical axis
Line graph
53
Type of graph: Similar to the histogram except that - Frequencies are plotted against the corresponding midpoints of the classes - Can depict more than 1 one distribution
Frequency polygon
54
T/F: frequency polygon is an open figure
F (closed)
55
Type of graph: Show relationship between two quantitative variables
Scatterplot
56
Type of graph: Gives rough estimate of the degree of correlation between the variables
Scatterplot
