Sample and Population Target audience all businesses in Canada (that consists of at least one employee) 15 000 out of 900 000 business in Canada
7
Sampling Method and Bias Systematic Sampling About 2% of the target population’s answers in the data (15 000 out of 900 000 =1.67%) Sampling Bias Sample does not accurately represent population Possible cherry-picking (census samples entire population but population is too large)

Payroll Employment Not normally distributed (not bell curve) Skewed LEFT
9
Independent Variable- Payroll Employment MEAN: 13,659.51 MEDIAN: 13,751.55 MODE: #N/A (numbers not repeated) Standard Deviation: 1051.02
10
Average Weekly Earnings Not normally distributed Skewed RIGHT
11
Dependent Variable- Average Weekly Earnings MEAN: 735.94 MEDIAN: 723.49 MODE: #N/A (numbers not repeated) Standard Deviation: 82.53
12
Two-Variable Statistical Analysis R= 0.949424471 R= Correlation Coefficient R² = Coefficient of Determination
13
Conclusion As payroll employment increases, the average weekly earnings increase Why: Strong positive linear correlation shows an increase in both variables
14
Further Analysis Survey and data collection should be done in other countries for comparison of economic status between businesses in different locations Comparison will indicate which country provides the highest job opportunity and income earned Data collection of unemployment should be taken into consideration to indicate which country will provide a more stable and successful life for individuals
