I assume that you came here from the link of Hypothesis! This means that you either haven’t learn or have completely forgotten the advanced hypothesis facts!
You need to learn the difference between directional and non-directional hypothesis!
This is a hypothesis that predicts how the I.V. will influence the D.V.
An example of this is: “A child will have higher levels of attachment to a parent if they are given extra skin to skin contact.” (This is actually a study you need to know if doing that attachment section and can be found here.)
This is a directional hypothesis because it states how the I.V. will be influenced.
This is the opposite of a directional hypothesis in that it does not state how the behaviour will change.
“There will be a difference in the level of attachment if they are given extra skin to skin contact.”
