# Hypothesis Testing

*Null hypothesis (H₀) is a claim of the status quo — that there is no difference or no effect.*

Step 1 · Formulating a null hypothesis and its alternative hypothesis

H₀ There is no difference between men and women in the frequency of internet use.

H₁ Men and women show different internet use behavior.

![IN_m ≠ IN_f](/principles-of-survey-research/media/ht_in_ungleich.png)

Null hypothesis (H₀) is a claim of the status quo — that there is no difference or no effect.

Alternative hypothesis (H₁) claims the opposite — that there is a difference or an effect.
