Deciding on a research question

Deciding on a research question

1. Know the aim of the research

2. Research hypothesis

3. Alternative or experimental hypothesis is one that states there is a statistically significant relationship between two variables

   • The null hypothesis is the opposite of this. It says there is no statistical significance between the two variables. It's the hypothesis that the researcher is trying to disprove

4. Directional hypothesis- researchers predict the direction or effect one variable (independent) will have on the other (dependant) be it positive or negative e.g. Better

   • Non directional hypothesis- researchers predict that the independent will affect the dependant but without stating the direction

5. Independent variable- the one condition you change in an experiment Dependant variable- variable being tested and measured

6. Co- variables- the relationship between two variables, which vary and are measured but neither are controlled by the researcher

7. Operationalisation of variables- is how you will define and measure a specific variable as it is used in the study

8. Confounding variable- factors that are related to the independent variable and affect the dependant variable

   • Extraneous variable- any factors that are in the experiment but not being studied
