Group 1TITLE• Provides a brief description of

the contents of the table.• It should be concise and include

the key elements shown in the table, for example, groups, classifications, variables, etc.

• Always at the top part of the table

• Keywords that allow you to establish an order to the data.

• Should be written in the singular form

• The first letter of the first word should be capitalized.

Table Body

• Actual data in a table occupying the columns, for example, percentages, frequencies, statistical test results, means, "N" (number of samples), etc.

A public opinion survey explored the relationship between age and support for increasing the minimum wage. The results are summarized in the two-way table.

In the 21 to 40 age group, what percentage supports increasing the minimum wage?(A) 12.5% (B) 20% (C) 25% (D) 50% (E) 75%

• A visual representation of a relationship between, but not restricted to, two variables.

• Commonly consists of two axes called the x-axis (horizontal) and y-axis (vertical).

GRAPH

Things to Remember in

Making Graph

Accurately shows the factsGrabs the reader's attentionHas a title and labelsIs simple and uncluttered

clearly shows any trends or differences in the data

is visually accurate

Types Of

Graph

Line Graph • Scale line graph:

represents frequency distributions over time

• Y-axis represents frequency.

• X-axis represents time.

Figure 8.1. Trends of Dropout Students in Public Schools in Philippines from Year 1991 to 2000.

Y-axis should beshorter than X-axis

Start the Y-axis with zero

Select an interval size

Example

Bar Graph • Uses differently

coloured or patterned bars to represent different classes.

• Y-axis represents frequency.

• X-axis may represent time or different classes.

Make bars the same width

Arrange categories that define bars ina natural order

Length of bars should beproportional to the frequency of event

Example

Clustered Bar Graph • Bars can be

presented as clusters of sub-groups in clustered bar charts.

• These are useful to compare values across categories.

• They are sometimes called stacked bar charts.

Show no more than three sub-bars within a group of bars.

Leave a space between adjacent groups of bars.

Example

Use different colours or patterns to show different sub-groups for the variables being shown.

Include a legend that interprets the different colours and patterns.

Histograms • A representation of

a frequency distribution by means of rectangles

Width of bars represents class intervals

Height represents corresponding frequency

Pie Chart• A circular (360 degree)

graphic representation• Compares subclasses

or categories to the whole class or category using differently coloured or patterned segments

Scatter Plot• A scatter plot is a two- or

three-dimensional plot that shows the joint variation of two (or three) variables from a group of observations.

• The coordinates of each point in the plot correspond to the data values for a single observation.

Student

Item Item Analysis

Pictographs• Diagrams that show and

compare data by using picture symbols.

• Each of these symbols corresponds to a specific quantity and is repeated a number of times.
