Explanation / Answer

q.31 d) as the sample selction is included in the methodology part of the paper.

q. 32 d) as the techniques used to collect data and analysed wuld be briefly describe din the discussion session. It would also be described in the method section but it would be more in detail and would be in future tense.

q.33 d) None of the above; as the correlation never talks about a causal relationship between two variables; though being a positive relationship describes that as mindfulness increases, empathy also increases.

Q.36 a) there is a 5% likelihood of getting a significant score by chance even though there was no effect;

It was Fisher who suggested giving 0.05 its special status. Page 44 of the 13th edition of SMRW, describing the standard normal distribution, states The value for which P=0.05, or 1 in 20, is 1.96 or nearly 2; it is convenient to take this point as a limit in judging whether a deviation ought to be considered significant or not. Deviations exceeding twice the standard deviation are thus formally regarded as significant. Using this criterion we should be led to follow up a false indication only once in 22 trials, even if the statistics were the only guide available. Small effects will still escape notice if the data are insufficiently numerous to bring them out, but no lowering of the standard of significance would meet this difficulty.

Q.40 K) Ordinal Scale; a scale on which data is shown simply in order of magnitude since there is no standard of measurement of differences:
