Section A

The importance of statistical mode in the nominal data as it provides larger amount of nominal results in that particular frequency. Because in a frequency distribution of the data, majority of the values lie in the center, therefore, modal values certainly helps to provide a better central tendency in the nominal data.



S = 10.5 - 0.85 (3) = £7.95

S = 10.5 - 0.85 (10) = £2

S = 10.5 - 0.85 (8) = £3.7

At p = £12, S = 10.5 - 0.85 (12) = £0.3

It can be seen that increasing the prices continuously leading to a decline in the sales.

For the first wrapper item to be faulty the chances are 4/8 = 0.5

Now, it the first item is faulty, then 4/7 = 0.571

If the first item is not faulty, then 3/7 = 0.428

A data that has very close linear relationship but only one or two outliers can make the Pearson coefficient results misleading. Similarly, relationship between nominal variables should not be provided through Pearson coefficient as it is only for normally distributed continuous data.

Positivism is a school that says that the only knowledge is real scientific knowledge, and that such knowledge can only come from affirmation of positive theories through the scientific method. Positivism derived from the epistemology that emerges in France at the beginning of the nineteenth century in the hands of French thinker Auguste Comte and Britain's John Stuart Mill and extends and develops for the rest of Europe in the second half of that century. According to it, all philosophical and scientific activities should be carried out only within the framework of analysis of the facts real verified by experience. The person has to use these scientific and philosophical activities and undermines the framework for the further analysis. This would help the researcher to adopt all the work systematically and used these extensive techniques in an accurate and authentic way.

Filter questions are used normally used by the researchers to determine or confirm the consistency of the responses. The consistency helps the researchers to obtain the data which is free from errors? The biasness in error of data has increased the inconsistency in the data. For this purpose, the filter question helps to remove the errors in the data and enhanced the consistency level of the data.

A snowball sample is a non-probability sampling technique that is appropriate to use in research when the members of a population are difficult to locate. A snowball sample is one in which the researcher collects data on the few members of the target population he or she can locate, then asks those individuals to provide information needed to locate other members of that population whom they know. Snowball sampling is tedious where to locate and then interpret. It's hard to use this sampling technique to the whole population, so in this situation we choose random samples and obtains the results on the behalf of these selected ...
