What is your research question?
Does face-to-face course delivery format leads to better student performance than online delivery format?
What is your hypothesis (both null and alternate)?
Null hypothesis: Face-to-face format leads to lesser or same performance scores as does online format.
Alternate hypothesis: Face-to-face format leads to better performance scores than online format
Is this a qualitative or quantitative design and why?
This is a quantitative design because performance is measured by numerical scores of students in statistics class.
Is this a descriptive, correlational, or experimental design and why?
This is experimental design because students would be selectively assigned to online or face-to-face format.
What would be an example of a variable for this study that could be measured on a nominal scale? Ordinal scale? Interval scale? Ratio scale?
Nominal scale: Gender of student (male/female)
Ordinal scale: Performance history of student (bad/good/excellent)
Interval scale: Age of student
Ratio scale: Test score
Once you have collected your data, would you use inferential or descriptive statistics and why?
We would use inferential statistics because we’d be generalizing the results if a format is better than another based on only a small sample from my statistic class.
Create a sample frequency distribution for one of the variables. Choose either a simple or grouped frequency distribution and explain your choice.
|Score class |Frequency of students in online format |
|=75 |7 |
Grouped frequency distribution was chosen as summarizing student scores by specific ranges gives better idea of overall performance than individual scores.
