Let me see how much I can remember...

Alternative hypothesis: This is when you predict that the IV will have an effect on the DV, or if there is a correlation that there will be a relationship between two co-variables. There are two types which I will explain.

One tailed: This is when you predict that the IV will have an effect on the DV and also in what direction.

Two tailed: This is when you predict that the IV will have an effect on the DV but not necessarily in what way.

Null hypothesis: This is simply when you predict that the IV will have no significant effects on the DV, or that there will be no relationship between two co-variables in the case of a correlation, and any effects/relationship will be due to chance.

Hope I covered everything for you.
