Research Projects (A&F) tutorial topics (session 2) Spring 2024

 Research projects (A&F) tutorial  topics (session 2) Spring 2024 


First of all: a checklist to evaluate acceptability of the research proposal and a note on how to refine research objectives in your proposal: an illustration.


Also take a look at some examples of research objectives.


The main theme is correlation analysis



1. On covariance [video]; demonstration of Excel
a. basic concept of correlation video: understanding correlation.
b. note the difference with causal relations. [also study the video on causal relationships]
d. on mediators and moderators & control variables in correlation modelling. (further discussion of the mediator under the topic of intervening variables).
1.1 scatter diagram
*** basic tutorial video on scatterplot and linear correlation
(also refer to: https://www.excel-easy.com/examples/trendline.html), and coefficient of determination. A related video on the coefficient of determination/ correlation; a video on coefficient of determination and another one on the coefficient of correlation (steps).
*** on Simpson's Paradox [video]; a note on Simpson's paradox.
1.2 Data->data analysis -> regression


2. Videos: 
2.1 * the normal distribution./ * understanding the central limit theorem./ standardized normal distribution./ standard error briefing 1/ standard error : briefing 2.



3. Correlation hypothesis statements
3.1. Examples





For formulation of one-tailed test, some clarification about the null hypothesis related to correlation:
a. for right tailed test, use b ≤ 0 [b less than or equal to 0]
b. for left tailed test, use b ≥ 0 [ b is greater than or equal to 0]

3.5. A video on falsification.


4. On multiple regression analysis
4.6 For students interested in panel data regression analysis, study this e-resource on panel research design.


e-resources:

Two videos on study of research validity: internal validity and external validity & internal validity.
