In True and False questions, if you decide that the answer is False, you need to provide a logic / reasoning for your decision. 1. Reliability is often referred to as (2 marks) 2. It is possible to make inferences that are valid, but not reliable. T/F (1 mark) 3. When we use nominal scale, the relative size of the numbers assigned to the objects reflect the amount of attributes the objects possess, and allow them to be rank-ordered. T/F (1 mark) 4. Developmental research captures the degree and direction of relationship between two different variables, as measured for one sample (group). T/F (1 mark) 5. In experimental research (True experimental designs) we as researchers do not need to worry about control of extraneous variables. T/F (1 mark) 6. When there is a high correlation between two variables (i.e. number of hours spent studying and grades on the final), we as researchers can conclude that there is a casual relationship between the two variables being correlated. (T/F) (1 mark)
