3 Ways of Presenting Data
* Textual
* Tabular
* Graphical
3
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Textual Presentation
* is putting important figures in the text of the report
* figures may be summary statistics like the minimum, maximum, mean, median, standard deviation, percentage,
or total
* allows us to highlight the significant figures of the study
* it confirms deductions and answers to the research problem

Example of Textual Presentation
In terms of relative data availability for progress monitoring of the Millenium Develoment Goals, the Philippines ranked first in 2003 among the 11 countries in the ASEAN region. Based on the 2003 report of the United Nations Economic and Social Commission for Asia and the Pacific (UN-ESCAP), the Philippines obtained a rating of 27.9% followed by Thailand with 25.2% and Indonesia with 24.6%. The Philippines ranked fourth among all countries in the Asia and the Pacific Region, with Australia topping the list with 29.1%, followed by Japan, 29.0%, and Republic of Korea, 28.7%. According to the UNESCAP, the theoretical maximum is for a country to have 767 data values (59 series x 13 years) and a country is counted to have data available when data exist for one or more years.

Tabular Presentation
* Arrangement of figures in rows and columns for easy reading and analysis
* It allows us to compare and look for relationships among the variables of interest
* The table can have frequency counts, proportions, percentages, and other summary measures such as totals and averages.
6
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Formal Statistical Table
* contains all the important parts of a table like table number, table title, head note, stub head, box
head, column headings, footnotes, source notes, etc.
* can stand alone even without an introductory statement.

Definitions of the Different Parts of a Table
Heading consists of the table number, title, and head note. It is located on top of the table of figures.
Table Number identifies the position of the table in a sequence.
Table Title gives the subject, classification, time, and area segments.
Head note specifies the unit of measurement of the data and may provide additional explanation about the figures in the table. It is located below the table title and above the top cross rule of the table.
8

Field is set of numerical figures in the table.
Line is a row of cell figures. Column is a column of cell figures. Cell is the numerical figure in the intersection of a row
caption and column heading.
Footnote is an explanatory text about a specific part or the whole table. Its position is at the bottom of the table.

Graphical Presentation
* It is a good means of communicating the numerical figures found in tables
* Charts facilitate analysis when it reveals probable relationships among variables
* It allows comparison of different series or groups
* Placing figures in charts permits us to validate conclusions made in the study.
16
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Notes: * Charts show only approximations and the general picture of the data set.* A good chart must be accurate, clear, simple, professional looking, and has a well-designed layout.* The arithmetic scale should have equal increments to represent equal numerical units.* The chart should have no visual illusions with the incorrect use of shadings or patterns.* We should put chart titles, scale figures and labels, and legends, if necessary.
17
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Types of statistical charts
* line chart
* vertical bar chart
* horizontal bar chart
* pictograph
* pie chart
* statistical map
18
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Definitions of Parts of a Chart
Chart Title * gives the subject, data classification, time reference, and area segment of the data set * located above or below the chart
Coordinate Axes * are the horizontal and vertical axes * spacing of the units may be different for the horizontal and vertical axes but must remain constant within the same axes.
Point of Origin * is the intersection of the horizontal and vertical axes.
19
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Scale Divisions * are the ticks to denote the scale points of the horizontal and vertical axes Grid Lines or Coordinate Lines * may be horizontal or vertical
* guides the reader in reading the numerical figures * must be lighter than the curves on the chart to maintain the focus on the chart * choice of horizontal or vertical grid line depends upon the type of chart.
20
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Scale Figures * run from left to right for the horizontal axis and from bottom to top for the vertical axis * use multiples of five or other easy to work with multiples for scale values * for big scale values, limit the number of digits of the scale figures to one or two, then; place the unit of measurement in the scale legend * position the scale figures near the coordinate axes * scale figure of the vertical axis starts with zero (for line chart and vertical bar charts) * if we only need the upper part of the coordinate fields to portray the data, we still retain the zero but exclude the lower part of the figures by putting a break on the vertical scale

Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Scale Labels or Scale Legends * describes both horizontal and vertical axes
Curves * represent the plot of the data series * differentiate several curves by using different patterns or colors. Curve Legends * give the type of data series * legend symbol follows the color or patterns selected for a particular curve * we prefer the use of curve labels than curve legends.
23
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009

* brief explanation to any part of the chart
* located at the bottom of the chart
Source Note
* indicates the source of the data

Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Line Chart
* appropriate for time series data
* emphasis is on the movement
* shows trends, patterns, forecasts
* applicable for one or more time series data for comparison purposes
25
Statistical Research and Training Center Training Course on Basic Statistics for ResearchAugust 24 - 28, 2009
Notes for Line Chart:
* put the variable of interest on the vertical axis and the time on the horizontal axis
* put appropriate scale legends for both axes
* position the scale figures on the tick marks
* ratio of height of width should be 2 to 3 or 3 to 4

* if the observed values are small, use multiples of 2* put a scale label to identify the variable of interest* put horizontal grid lines* for one series of data, use only one color or pattern* for two or more series of data, use different colors,
shadings or patterns* avoid wavy or unconventional patterns
