True or false 6. A normality test compares the distribution of the research data with that of a theoretical sample. 7. A test of difference can only be carried out with parametric data. 8. A chi-square test can only be carried out between nominal variables. 9. Regression analysis can only be carried out if the correlation between dependent and the independent variables is linear. 10. Regression analysis can only be carried out if there is no perfect multicollinearity between the independent variables. © Jill Collis and Roger Hussey, 2009 Business Research

Fill the gaps 1. A random sample is a representative subset drawn from the population. 2. A number that describes a sample is called a statistic 3. A number that describes a population is called a parameter. 4. Parametric tests are underpinned by four assumptions about the characteristics of the distribution of the population. 5.
