1. Regarding the standard sizes of the strength of correlation or the correlation coefficient, do they also apply to negative correlations? For example, is it possible to obtain results like a coefficient of -.10 or -.45?

2. What exactly is the degrees of freedom in relation to the 2 variables in a correlation study?

3. If it’s the degrees of freedom of the variables, how do you calculate those variables’ degrees of freedom?

Part 1 (Video 1 – 6)

1.     When do we use spearmen rho and correlation matrix?

2.    Why we use the word positive extreme or positive skew to describe while most students have low motivation or low score?

3.    How do we interpret the result? Bases on statistic in the video the (-2.49) is not mentioned but we interpret if the skewness is below or above -1 +1, the data is approximately normal skew. Is the -1 and +1 minimum and maximum range formular we use to calculate?

4.    What does it mean by no correlation of the data?

5.    Is there any effect on the result of the research if we remove a pretty big amount of the outliers. For instant, among the 10 student, 6 students get high scores 8 and 9, but 4 students get zero scores.

6.    What does it mean by none linear relationship?

1. What are the correct steps that we need to follow in order to conduct a correlation research? And how do we interpret both each step along with its data?

2. What are the differences between Pearson and Spearman theory?

3. How do we know if the output data in getting skewness in SPSS is correct or wrong? And whether the data is skewed or not, which theory should we follow based on the output data?

4. Beside positive, negative, and zero correlations, are there any other type of correlation? And if there are, what are their role in this type of research?

5. What is the appropriate sample size in doing research involving Pearson Correlation? And what could happen if the sample size is too small?

6. If there are outliers, should we remove them from the data or keep them in? And how do they affect the results of the correlation?
