Hypothesis writing

[Rajlaxmi Garg]

I want to write a hypothesis to show X negativity affects Y.

What is the best way to write it?

H1 : X significantly reduces Y

Or

There is a negative impact of X on Y

Or 

X negatively impacts Y.

Or 

There is significant negative relationship between X and Y

Or 

X is negatively related to Y

Q2.

Now if results show Beta value negative ( which means X reduces Y) but P value is not significant, so will this hypothesis be rejected or accepted??

Q3And if beta is positive and p value significant than we will say, hypothesis not accepted??

Dear Rajlaxmi

Plz watch the first 3 videos of this playlist: Research Methodology

Statistics does not know the English language, it looks for the number of vars, your intention, role of a var and the way it is measured.

1. All 5 ways of writing hypothesis are correct

2. p>0.05 indicates Null hypothesis accepted, hence whatever beta value you get is as good as zero.

3. p<0.05 indicates Null hypothesis rejected and the positive beta will indicate that your directional hypothesis is also rejected.

Best wishes
