Aims and hypothesis Flashcards
(6 cards)
What is the aim of a study ?
A statement saying what the researcher intends to investigate
For example - What impact does drugs have on treating OCD
What is the hypothesis ?
An idea that can be verified/disproven by an investigation
What the researcher thinks the result is likely to be.
What is a directional hypothesis
Predicts the direction of the relationship or difference (e.g., positive, negative, increase, decrease, higher, lower).
One-Tailed: Refers to the fact that the test only looks at the results in one specific direction.
Precise: Specifies the expected outcome with more detail than a non-directional hypothesis.
What is a non-directional hypothesis ?
Predicts a difference: It suggests that a relationship or association exists between variables.
Does not specify direction: It doesn’t predict whether one variable will be higher or lower. Not predict relationship between variables
Uses broad terms: It often uses words like “effect,” “change,” or “difference”.
Used when there is no prior knowledge: It’s commonly used when there’s no existing research to suggest a specific direction of the relationship (Two tailed)
What is a null-hypothesis ?
There is no relationships between the variables being studied.
The treatment being studied has no effect on the outcome.
No difference between groups
What is falsifiability ?
For a theory to be considered scientific it must be able to be tested and proven as true/false
Make sure the theories are constantly being tested for proper understanding.
