-answers research question

sampling design

-kung paano iggather data

statistical design

part of research design that is concerned with the question of how the information and date gathered are to be analyzed

operational design

part of research design that involves techniques which the procedure are satisfied with sampling

research design

-a scheme or plan of action for meeting objectives

-a blueprint for conducting a study that maximizes control over factors that could interfere with the validity of the findings

to answer the research question

what is the purpose of research design?

true

T/F: the aim in research design is to produce reliable and valid data

reliability

refers to the consistency, stability, or dependability of the data

validity

refers to data that are not only reliable but also true and accurate

-an instrument is able to measure what it is supposed to measure

descriptive design

type of basic research design

-mc method used

-inquiring about the prevailing conditions of events, objects, or people

exploratory descriptive design

type of descriptive design

-in depth exploration of a single variable or concept

-demographic data

comparative design

-1 sample size

-intensive exploration of single unit of study

-pre-experimental

-true-experimental

-quasi-experimental

3 types of experimental design

✅post-test

❌pre-test

❌control group

describe one-shot case study

✅pre-test

✅post-test

❌control group

describe one group pre-test post-test design

1. complete

2. no tx

3. no pre-test

4. no pre-test & tx

describe solomon four-group design

counter-balance design

type of experimental design

-all groups receive all tx but in different order

time series analysis

type of experimental design

-repeatedly pre-tested

-tx

-repeatedly post-tested

non-equivalent control group design

type of experimental design

-like pre-test post test control group

-but lacks random assignment
