collection of data and aims to test theories and hypotheses and / or to produce new theory. Researchers usually use questionnaires or surveys in order that they can make generalisations‚ therefore‚ the surveys are usually based on carefully selected samples. Questionnaires consist of the same set of questions that are asked in the same order and in the same way in order that the same information can be gathered. Questionnaires can be: 1. Filled in by the participant 2. Asked in a structured and

concepts that are essential to understanding the statistics of the life and health sciences. The idea that a sample is illustrative of a given population‚ since a sample is derived from a specific‚ yet larger pool of information seems factually representative. Random sampling aides research in that it applies experimental design to the selection process and is the fairest means of sample collection‚ providing equal chance to the members of a given population being signified.

situations‚ fairly easy to run‚ no order effects from P’s becoming skilled‚ bored or fatigued. Disadvantages: Individual differences between groups may distort findings (random allocation to conditions helps reduce this risk); require fairly large sample size because each P is used only once. Repeated measures design Each P is involved in all conditions‚ the same Ps are used in experimental and control groups. Advantages: Economical in use of Ps‚ no risk of participant variables confounding

3.4 Sample Size Researchers identify the sample size of the EPIC operation employees by using Senkara‚ U. and Bougie‚ R. (2013) sample size of target population table. A sample size of 120 respondents was generated from operation employees by using non probability sampling technique in which units of the sample are selected on the basis of the convenience sampling. Using this sampling technique was to ensure every unit in population had equal chance to be selected as the sample of study
