BDSC2000

This assignment requires you to make graphs and do analyses in Prism and to use the Excel dataset
file called “Class data” that you will find just below the link to this document on FLO.
You will provide your answer as a Word document into which you will have pasted your graphs and
analyses from Prism.
The questions we want to answer are:
1. Are males significantly taller than females in our class?
2. What correlates with height in our class?
3. Do people eating more vegetables report their health as better?
Question 1: Are males significantly taller than females in our class?
Make a correctly labelled graph of the data showing the means and appropriate error bars as well as
individual values. (4 marks)
Carry out the appropriate analysis to test whether the mean male height is significantly different
from the mean female height. Report exactly what test you used and why, as well as the p value and
explain what it means in this case. (2 marks)
If I gave you the heights of students in another 30 classes at Flinders, how would you test whether
your class was unusually small or tall? Why would you use this approach? (2 marks)
Question 2: What correlates with height in our class?
Carry out the appropriate analysis to test whether Height correlates with Resting Pulse Rate in our
class. What do you conclude? (2 marks)
How much of the variation in resting pulse rate in our class is explained by the variation in Height?
Show the appropriate graph to illustrate this (2 marks)
Carry out the same analysis with other variables to find one that DOES and one that DOES NOT
significantly correlate with height in our class. Show the linear regressions and analysis to justify
your conclusions. (3 marks)
Question 3: Do people eating more vegetables report their health as better?
Carry out the appropriate analysis to test whether people eating more vegetables (>2.5 serves/day)
report their health as better (good or above). Show the data, the analysis and give the appropriate
interpretation of the result. (5 marks)
