Given below are two statements - one is labelled as Assertion (A) and the other is labelled as Reason (R) : Assertion (A) : A researcher can draw a definitive conclusion even if there is a little evidence to support it. Reasons (R) : Statistical test of significances helps a researcher in drawing logically correct inferences from the data. In the light of the above statements choose the correct option :
(A) is false, but (R) is true
To solve the given question, let's evaluate both the assertion and the reason provided:
In research, drawing definitive conclusions requires substantial and reliable evidence. A little evidence is generally insufficient for drawing definitive conclusions, as conclusions need to be based on a comprehensive analysis of adequate and valid data. Therefore, assertion (A) is false.
Statistical tests of significance are indeed critical in research as they provide tools to determine if the results are significant or if they may be due to chance. These tests help in assessing the relationship between variables and allow researchers to make logical inferences. Thus, reason (R) is true.
Now let's consider the options based on our analysis:
In conclusion, the correct answer is: (A) is false, but (R) is true.
Given below are two statements:
Statement I: The p-value of a test depends on sample size.
Statement II: An important difference may not be statistically significant if the sample size is too small.
