The purpose of a survey is to?

Quantify population characteristics.

1

Comparative studies are done to?

Quantify relationships between variables.

2

A type of research that can involve quantitative information and can describe categories of qualitative information such as patterns.

Descriptive research

3

It is the collecting of information on all individuals.

Census

4

Surveys that collect date on only a portion is called...

Sample

5

This research involves gathering data that describe events and then organizes, tabulates, depicts, and describe data.
Often uses visual aids such as graphs and charts.

Descriptive research

6

Refers to the nature of the research question

Descriptive research

7

Uses historical data to make comparisons based on risk factors or exposures that occurred prior to the event

Cohort studies (retrospective)

8

A study that follows a group of cells, animals, or patients with different exposures until some point in time where something happens or the study is terminated

Cohort studies (prospective)

9

A study that compares the characteristics between two groups, usually one that has a condition or disease is compared with one that does not have the condition or disease.

Case-control study

10

Unique kind of case-control study.
Type of design used if cases cannot be identified or if the prevalence of the disease or condition needs to be determined.

Cross-sectional studies.

11

A research that is done to learn about the relationship between an explanatory variable and response variable.

Comparative research

12

Type of comparative study that investigator assigns the exposure to one group leaving the other non-exposed (placebo)

Experimental

13

Type of comparative study that investigator classifies individuals as exposed or non-exposed without intervention

Non experimental

14

A study in which conditions are controlled and manipulated by the study investigator

Experimental study

15

Type of experimental study that is conducted by trying a new treatment on some experimental units. Any benefits or harmful effects seen in the study units in will be ascribed to the new treatment

Uncontrolled studies

16

Type of experimental study that the intervention is compared with the other treatment. Used for comparison.

Controlled studies.

17

Is the treatment or exposure that explains or predicts changes in the response variable

Explanatory variable

18

Is the outcome or response being investigated

Response variable

19

Is the distortion in an association between explanatory variable and response variable brought about by the influence of the extraneous factors

Confounding

20

Must be collected in a way to allow generalizations to be made to the entire population, the sample must entail an element of chance.

Simple random sample

21

Entire aggregation of cases that meets a specific set of criteria.

Population

22

Subset of entities that make us the population

Sample

23

Most basic unit about which information is collected

Unit/element

24

Listing of accessible population from which you'll draw your sample

Sampling frame

25

Selection of a number of study units from a defined study of population

Sampling

26

Includes all the characteristics of the population from which it is drawn

Representative.

Note: representative sample is like population only smaller.

27

Type of non probability sample that uses the most convinient available people as study participants.

Convenience sample

28

This is the identifying of strata of the population
And specifying the proportions of the elements needed form various strata of population

Quota

29

Each unit of sample is chosen by chance

Probability sample
