STAT 1770 - Tutorial 1 Question 1 Suppose we take a random sample of the oral temperature of all 68 registered students in this class and that we are trying to estimate the average body temperature of the population. a) How many observations are there in our dataset? b) What is the variable in this scenario, and is the variable numerical or categorical? c) What would an example of the larger population be in this example (there could be multiple correct answers here)? d) Is the data qualitative or quantitative? If the data is quantitative, is it discreet or continuous? Question 2 In 1971 Statcan surveyed Canadians to about the language spoken most often at home. The results showed 14446235 individuals spoke English at home most frequently, while 5546025 individuals spoke French at home most frequently. a) Does our data represent a sample or a population? b) Is the variable in this dataset numerical or categorical, if it is categorical, what are the possible levels? c) Create two tables to display the data; the first should show nominal values and the second should show the percentage. d) Construct a barchart to display the results of both tables with appropriate scales (the table does not have to be exactly to scale, but should be roughly representative and the axis values should reflect the data). Question 3 For this question I'd like you to be creative. a) Give an example of qualitative data. b) Give two examples of quantitative data, one discreet and the other continuous. 1
