Data Presentation Flashcards
→ Part of descriptive statistics – Sumamrizing and presenting data
→ Purpose – presenting the data and result when research is done
Data Presentation
3 types of Data Presentation?
- Narrative (Textual)
- Tabular
- Graphical
T or F
is it possible to use and combine different type to present data?
T
Can be used combination of any (e.g. narrative, tabular)
Three Types of Data Usually Tabulated
- Frequency Distribution
- Correlation Data
- Time Series Data
T or F
in every table, narrative, or graphical, there is a equal or possible graphical representation?
T
yung data na ginagamit sa graphical rep, came from table, narrative,
if u see this card
Familliarize urself with the simple exampe for narrative and table
Narrative - T or F
Narrative form takes a lot to decipher?
T
Too many letters or words
Narrative - T or F
Narrative are for longer summaries
F
its only for short summaries!
TOO long will not take the gist, i table na
Reason for Tabulation ?
Data are tabulated to make them easier to understand
Tabulation - T or F
it is not organized, but concise and compact
F
it is Organized, Concise, abd compact when there a lot of data
Datas are grouped according to some scale of classification, where the sum of the entries is equal to the total.
Frequency Distribution
Freq. DIstribution - T or F
There is a no characteristic to be categorized?
F
need ma-categorize
Freq. DIstribution
The figures may either be in ?
- actual numbers
- in percent
- or in both
Freq. Distribution
what are the scales used?
- Qualitative
- Quantitative
- BOTH
Freq. Distribution
when classifying qualitative scale, what should you do?
an individual is put into one or another part of the scale according to some more or less readily recognizable attribute or characteristic
Freq. Distribution
in QUALI the presentation of data in table should be?
highest to lowest
In the data MALE nauna (exception to the rules) if SEX categ
Freq. Distribution - T or F
The 2 tables can be expressed in percent and the data will still be of the frequency distribution type
T
Freq. Distribution - T or F
The two qualitative scales can be combined and the result will still be a frequency distribution.
T
one way table is for?
1 categorical variable
a visual representation of the possible relationships between two sets of categorical data.
Two-way frequency tables
give me some examples of QUALI scale
- age
- weight
- blood pressure
- scores
Freq. Distribution - T or F
When classifying according to a quantitative scale, the individual is assigned to a number in accordance with some measuring device.
T
may mag memeasure daoat
T OR F
IN DATA IT IS IMPORTANT TO OVERLAP!
F
to not overlap!
when do we use multiple response table?
if the answers is more thant the sample population
may choices sila and can pick one or more okay? okay
Used to compare two or more frequencies.
Correlation Data
Simple presentation without attempts to present rates or ratios make the data a pure frequency distribution.
Correlation Data
If rates or ratios are calculated and included in the table, summation of rows or columns will not give the total
hence the data lose their frequency nature but the table offers a better
Correlation Data
is there a total row or columns in a correlation data?
wala, only talks about correlations!
Variable changes over a period of time is the ones being presented
Time Series
What are the variable under TIME SEIRES?
TIME
it changes can be year, month, etc as long it tells movement of time
The process of tabulation is a process of ?
Classification
When using tabulation, what is the sequence?
ORDERLY
kayya concise and compact ang table
Enumerate the parts of a table
- Table No.
- Title
- (Headnotes)
- Row and Column Headings
- Stubs
- Cell
- Body of the table
- Footnotes
- Source
identify the element of the table
- The word table should be capitalized
- Arabic numbers
- If related, use the decimals – e.g. 7.2, 7.3
Table no.
identify the element of the table
Uses dash (-) before the Title not PERIOD
Title
identify the element of the table
it should contain:
* WHAT
* WHERE
* WHEN
Title
this should answer the questions
identify the element of the table
- First letter of the important words are capitalized
- If 2 lines, should be indented to appear inverted pyramid
Title
identify the element of the table
this is used to clarify something in the title
Mostly unit of measurement
Headnote
nasa luob ng parenthesis and called secondary caption
identify the element of the table
Basis for their classification
Row and Column Headings
identify the element of the table
To clarify the contents of the table
Footnotes
identify the element of the table
If borrowed, there should be acknowledgment

kindly go over the Sample of a Frequency Distribution Table for Ungrouped and grouped Data
Guides for Frequency Tables
Be sure that the classes are
mutually exclusive
Guides for Frequency Tables - T or F
Include all classes, even if the frequency is zero
T
Still include the classification
Guides for Frequency Tables
Try to use the same - - - - - for all classes
width
Guides for Frequency Tables - T or F
Select convenient numbers for class limits
T
Guides for Frequency Tables
Uses how many classes
Between 5 and 20 classes
Guides for Frequency Tables - T or F
The sum of the class frequencies must equal the number of original data values.

Is it clear to what the ____ refer?
totals
Brains absorbs VISUAL better than narrative
Graphical Presentation
Whenever verbal problems involving a certain situation is presented visually, it makes it easier for the reader to understand the problem and attempt its solution
Graphical Presentation
imilarly, when the data are presented pictorially (or graphically) before the learners, it makes the presentation?
eye-catching and more intelligible
easily see the salient features of the data and interpret them
What can you see in a statistical graph?
either
* Series of lines joined together
* Bars
* Enclosed Areas
drawn to represent certain statistical information under the consideration
The purpose is to convey a simpler idea of what the statistical table contains

significant trends or patterns

The Statistical Map
if u see this card
Familairze yourself with the concept of the statiscal map using the samples
Graphs not only quickly inform us; they can also quickly?
Deceive us
Deceives us in a way that it stretched the graph so it shows “skyrocketing” the distance is not proper
Shrinking an Stretching the Axes: Visual Confusion
check niyo sample here
- The drawing was just bigger, deceives us with the visual
- If we see something big we usually correlates it with it more bigger data

Why use charts and graphs? - Lose or Gain
ability to examine numeric detail offered by a table
Lose
Why use charts and graphs? - Lose or Gain
ability to direct readers’ attention to one aspect of the evidence
Gain
Why use charts and graphs? - Lose or Gain
ability to reach readers who might otherwise be intimidated by the same data in a tabular format
Gain
Why use charts and graphs? - Lose or Gain
potentially the ability to see additional relationships within the data
Lose
Why use charts and graphs? - Lose or Gain
potentially time: often we get caught up in selecting colors and formatting charts when a simply formatted table is sufficient

ability to focus on bigger picture rather than perhaps minor technical details
