2. Review Practical Research 2: Choosing your topics and titles 2

3. Each person/thing we collect data on is called an observation. In our research work, these are usually people/subjects. Observation (participants) possess a variety of characteristics. Introduction A discussion on variables in research 3

4. If a characteristic of an observation (participant) is the same for every member of the group i.e. it does not vary, it is called a constant If a characteristic of an observation (participant) differs for group members it is called a variable .

9. Comparison Independent variables versus dependent variables Independent Variable are variables which are manipulated or controlled or changed. It is what the researcher studies to see its relationship or effects . Presumed or possible cause Dependent Variable are the outcome variables and are the variables for which we calculate statistics. This is the variable which changes on account of independent variable. It is influenced or affected by the independent variable Presumed results(Effect) 9

Observation (participants) possess a variety of characteristics. A variable is a concept or abstract idea that can be described in measurable terms. A variable refers to characteristics , qualities or attributes of a particular individual, object , or phenomena. 5. Age or income can be variables because these can take same values for same people or for the same values at different times.

TRUE A variable is a concept or abstract idea that can be described in measurable terms. TRUE A variable refers to characteristics , qualities or attributes of a particular individual, object , or phenomena. TRUE 5. Age or income can be variables because these can take same values for same people or for the same values at different times. FALSE

19. 19 ASSIGNMENT: 1) Review your research titles as a group. 2) Discuss with your members what would be the independent variable/s and the dependent variable/s of your study. 3) Write your answers in one (1) whole sheet of paper. 4) Share it in class.
