Question

Question 1:
a) what experimental design approaches are used to prevent
pseudoreplication.
b) If, after the research is completed, the researcher obtains a p-value of 0.06 What does this p- value signify? What should they do? Is there a way to salvage this experiment?
c) What does it mean when we say that a result is ‘statistically significant’?

please explain it briefly

Answer 1

(a) To prevent pseudoreplication, the following experimental design approaches are used generally-

1. We have to properly extrapolate the Sample Size.
2. We have to draw up a sampling frame for the primary sampling unit.
3. The response variable measurement with sufficient precision within each primary unit.
4. We must analyse the data using the average value for each unit.

(b) After a research, if researcher obtains p-value of 0.06, it means probability of obtaining the result under the null hypothesis is 6%. if p value is greater than 0.05, it is not statistically significant.

(c) When the null hypothesis is true, if there is a low probability of getting a large result, it is called "statistically significant".Generally p value less than 0.05 is statistically significant.
