31
Q

This study has two branches

  • Randomized Study
  • Non-Randomized Study
A

Experimental Studies

32
Q

Aims of Experimental Studies

A

To provide scientific proof of etiological factors which may permit modification or control of disease

To provide a method of measuring the effectiveness and efficiency of health services for the prevention, control, and treatment of disease and improve health of the community

33
Q

Under this branch if Experimental Studies are Clinical Trials and Control Trials

A 
Randomized Study 
(Experimental Studies)
34
Q

A study where people are allocated at random (by chance alone) to receive one of several clinical interventions

A

Randomized Controlled Trial (RCT)

35
Q

What is the meaning of RCT?

A

Randomized Controlled Trial

36
Q

One of the interventions is the standard comparison or control

A

Randomized Controlled Trial (RCT)

37
Q 
The control may be standard practice 
A placebo (“sugar pill”) or no intervention
A

Randomized Controlled Trial (RCT)

38
Q

This seeks to measure and compare the outcomes after the participants receive the intervention

A

Randomized Controlled Trial (RCT)

39
Q

Under this branch of Experimental Studies are:

  • Quasi Experimental Research
  • Field Trial
  • Community Trial
A

Non-Randomized Study

Experimental Studies

40
Q

This shared similarities with traditional experimental design or randomized controlled trial

It lacks the element of random assignment to treatment or control

A

Quasi-Experimental Research

Experimental Studies “Non-Randomized”

41
Q

Applies preventive interventions to healthy individuals

A 
Field Trial 
(Experimental Studies “Non-Randomized”)
42
Q

Applies intervention to aggregative units

A 
Community Trial
(Experimental Studies “Non-Randomized”)
43
Q

What is Data?

A

It is the observation of random variables made on the elements of a sample

44
Q

“The quantities (number) or qualities (attributes) are measured or observed to be collected and analyzed”

A

Data

45
Q

What are the two types of data?

A

Observational Data

Experimental Data

46
Q

Researchers collect data based in what is seen and heard

“Researchers should not interfere with the subject or variables in any way”

A

Observational Data

47
Q

Researchers produced this by measurement, test method, and experimental design

“Can have control over some variables”

A

Experimental Data

48
Q

What are the Methods of Data Presentation?

A
  • Textual
  • Tabular
  • Graphical
49
Q

Data gathered are presented in paragraph from

A

Textual

51
Q

This form of data presentation is a combination of texts and figures

(Methods of Data Presentation)

A

Textual

A

Graphical

61
Q

Examples of this method of data presenting are: Pie, Barr, Venn, Histogram, and Epidemic Curve

A

Graphical

62
Q

This Graphic Presentation is used to examine a relationship between two (non-sequential) variables

A

Scatterplot

63
Q

This Graphical Presentation is used where the x-axis represents some sequential variable like time or distance along transect

A

Line Plot

64
Q

This Graphic Presentation has two different y-axes

Primarily used in the same sorts of situations as line plot

You compare the pattern of change in two different types of variables

A

Double Y Plot

65
Q

This Graphical Presentation is either used to present means (and appropriate error bars) or counts of some sort including proportions and percentages

Can be horizontal or vertical

A

Bar Chart

66
Q

This Graphic Presentation combines features of line plots and stacked bar charts

This is generally used to show trends in time or space

A

Area Plot

67
Q

This Graphical Presentation is familiar to everyone but is relatively limited used for scientific figures

A

Pie Chart

68
Q

This Graphical Presentation lets you discover and show the underlying frequency distribution (shape) of a set of continuous data

A

Histogram

69
Q

This Graphic Presentation is a method of organizing raw data in a compact form by displaying the data in ascending/descending order together with their frequencies

A

Frequency Table

70
Q

This Graphical Presentation is a diagram of representing mathematical and logical sets

Common element is represented by the areas that overlap among circles.

A

Venn Diagram

71
Q

This Graphical Presentation is a visual display of the onset of illness among cases associated with an outbreak

A

Epidemic Curve

72
Q

What are the different roles of application of quantitative research to public health

A
  1. Survey Study
  2. Surveillance Study
  3. Observational Study
  4. Experimental Study
73
Q

This study is used to estimate the extent of the disease in the population

A

Survey Study

74
Q

This study us designed to monitor or detect specific diseases

A

Surveillance Study

75
Q

This study investigates the association between exposure and a disease outcome

A

Observational Study

76
Q

This study relies on the “natural” allocation of individual to exposed or non-exposed groups

A

Observational Study

77
Q

This study also investigates the association between exposure and disease outcome of individuals who are “intentionally” placed into treatment groups by the investigators

A

Experimental Study
