advantages of qualitative research design
;verify results
;filter out external factors and produce unbiased results
;verify qualitative researches and narrow down possible results
;variables can easily be manipulated
refers to the overall strategy that a researcher uses to logically and coherently integrate the various components of a study
research design
Disadvantages of qualitative research design
;time consuming in data collection
;difficult and expensive to do
;requires statistical analysis
;very little room for uncertainty
is the most common design that observes and reports certain phenomenon or shows a
picture of a group
descriptive research design
common study designs used in descriptive research design
comparative descriptive design; cross-sectional and
longitudinal designs
descriptive statistical tools used in descriptive research design
Mean, Median, Mode, and Percentage, Frequency
research design that seeks for connection between one variable and how it affects another variable but not a “cause-and-effect” relationship which means no manipulation of variables
correlational research design
common study designs used in correlational research design
descriptive correlational designs, predictive designs
statistical tools used in correlational research design
Spearman’s rho (Spearman’s r)
Pearson product-moment correlation (Pearson’s r)
research design that aims to infer the causes of a phenomenon which have already occurred
(ex-post facto) causal comparative research design
study design used in causal comparative research design
questionnaires
statistical tools commonly used in causal comparative research design
Wilcoxon Signed-Rank Test
research design that aims to establish a cause-and-effect relationships that it may or may not have a control group or subjects and subjects are not randomly assigned to groups
quasi-experimental research design
common study designs used in the quasi-experimental research design
pre and post-test designs
post-test only designs
interrupted time series designs
non-equivalent designs
statistical tool used in quasi-experimental research design
Mann-Whitney U test
aims to establish cause-and-effect relationships and randomly assign individual participants/subjects to the treatment and control groups
experimental research design
common study designs in experimental research design
pre-test-post-test control group designs
post-test only control group designs
Solomon four-group designs
statistical tools used in experimental research design
t-test for independent sample (unpaired t-test)
One-way Anova
two kinds of sampling
probability and nonprobability sampling
refers to the selection of a sample from a population is based on the principle of randomization
probability sampling
is a sampling technique in which the researcher selects samples based on the subjective judgment of the researcher rather than random selection
nonprobability sampling
types of simple random sampling
fishbowl technique
lottery method
sampling using table of random number
This method of sampling is done by taking every kth element in the population
systematic sampling
When the population can be partitioned into several strata (singular: stratum) or subgroups
stratified random sampling
