Group of answer choices

directional

non-directional

Answer 1

Solution:

Given:  It will take athletes more time to run 10 km [Run] than to swim 1.5 km [Swim].

A hypothesis statement is directional or non-directional depends on how it is stated.

If hypothesis statement says:

i) one group mean is less than other group mean, then it is directional statement and it is towards left side ( < )

ii) one group mean is greater than other group mean, then it is directional statement and it is towards right side (> )

iii) one group mean is equal to other group mean or in other words one group mean is different from other group mean, then it is non-directional statement, that means difference in means will on any of the side.

We have two groups Run and Swim.

It says it will take more time to run 10 km than two swim 1.5 km.

So it says one is more than other, thus this is directional hypothesis..
