1

Non experimental

Case studies (presentation of facts)
Single variable Research

2

Examples of single variation research

Population surveys
online surveys
Opinion polls
Descriptive surveys.

3

Multiple Variable Research

Archival research
Observational Research

4

Multiple Variable Research Correlational methods :

Survey research
validation studies

5

Variable Indenpendent

prior in time,

6

Dependent

the results

7

Independent

Influence changes in the dependent variable

8

Independent variale

Manipulated

9

Dependent

Measured

10

Control variable

What I keep the same.

11

What are extraneous variables

Exist in all type of studies

12

What is the Hawthorne effect?

Study participants know they are being studied and may report more problems than person's not in the study are consciously aware of.

13

DATA collection

Without manipulation, natural conditions

14

Reliability means

Consistency

15

Validity (can you replicate this study)

Capture variable of interest

16

2 types of population-sample relationships

Random
Convenience (purposeful)

17

Quasi and non-experimental

Can use convenience sampling

18

Stratified sampling

Sampling from subgroups in a population, sample percentile equal Work for equity and quality of representation. MORE RELIABLE and VALIDITY HIGH , especially if they are double blinded.

19

Cluster sampling

Target population is large and spread out

20

Sample from an available population

Convenience.

21

NULL hypothesis

Means insignificant or no relationship between 2 variables.

22

Alternative hypothesis

Means rejection of null hypothesis.

23

Claim : X cures Y
Null hypothesis

X doesn't cure Y

24

You can't accept

NULL hypothesis

25

Type I error

Not believing the truth

26

Type II is accepting

a false null, believing a lie

27

If the P is low

the null must go
