RANDOM TEXTBOOK RESEACH METHODS Flashcards
What is the hypothesis?
A hypothesis is just a prediction about what the scientist imagines(through educated guesswork) to be the relationship between two variables.
What is a variable?
A variable is a factor that can be changed and manipulated in ways that are observable and measurable.
What is the independent variable?
The independent variable is the thing you change or manipulate and it is this change that you can expect to lead to the hypothesis effect.
What is the dependent variable?
The dependent variable is the factor that changes as a result of the independent variable.
What is a positive correlation?
A positive correlation means that s the amount of one variable increases the other one does too.
What is a negative correlation?
A negative correlation means that as one variable increases the other decreases.
What is an issue with observational methods?
There could be observer bias.
What is the reliability?
Reliability is sometimes used to mean ‘consistency’, a reliable research technique that will yield the same results consistently if we were to repeat the measured time after time.
What is validity?
Validity refers to the extent to which a research technique actually measures the behaviour it claims to measure.
What is internal validity?
Internal validity refers to how much we can be sure that the findings are due to the variables under consideration rather than extraneous variables.
What is external validity?
External Validity considers how much the results from the psychological study can be more generalised more widely.
