Research is one of the subjects that most of us are having a hard time grasping. I failed this percentage of the NPTE big time when I took it the first time in June 2010. And it took me three sweeps of my research notes to for the subject to make sense.
I have been reading and doing my best on what to post about Research, however I do have some reservations on topics to post because of infringement from book authors and I do not want to do anything that might get me in trouble, if you know what I mean.
So here are just some suggestions on my end on what to study on research:
- Know the difference between Descriptive and Inferential statistics.
- Clear-cut examples of the following scales of measurement: Nominal, Ordinal, Interval and Ratio.
- Define and find examples of data collection and sampling techniques.
- What is an independent, dependent, random, controlled and covariate variables.
- What are the difference between Mean, Median and Mode.
- What is Sensitivity and Specificity.
- Find out the Confidence Intervals for the Mean, Variances and most especially Standard Deviation.
- An overview of different types of hypothesis testing (Type I and II error, Significance level, Hypothesis, z and t test).
- Definition and find samples of a Chi-square, Analysis of Variance, Analysis of Covariance
- Samples of different types of Research design(control Group, Control, Experimental, etc).
- Definition and samples of Validity. (Construct, face, Content, etc…)
Look at the samples presented for each of the topics listed above. Don’t try to memorize, but understand them.
Hope this helps!
