purpose of this memo is to describe the sampling process and illustrate how sampling can be used during an audit. This memo will begin by defining what sampling is‚ when it should be used‚ and the risks associated with it. The memo will then continue to describe the basic steps involved with sampling‚ define terms within those steps‚ and describe the use of sampling in the audit by identifying two situations in which sampling is used in an audit. Sampling is the objective of which is to make a statement

11 (i) SAMPLE DESIGN AND SAMPLING PROCESS Introduction Samples are parts or potions of population. A population is the specified total of study elements. A target population‚ also known as the universe‚ includes all the members of a real or hypothetical set of people‚ event or objects to which we wish to generalize the results of our research. A study population is that aggregation of elements from which the sample is actually selected. Sampling means selecting a given number

Single random sampling : a. Definition: Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample. Every possible sample of a given size has the same chance of selection; i.e. each member of the population is equally likely to be chosen at any stage in the sampling process. b

Exercise 36 Answers 1. Since the F value is significant‚ based on the p-value of 0.005 which is less than 0.05 which is sufficient to reject the null hypothesis. This suggests that there is a difference in the control and treatment groups. 2. Since the p- value is less than 0.05 and therefor the null hypothesis can be rejected. This presents that the mean‚ difficulty and mobility scores‚ must be different 3. The result was statistically significant with a probability score of p < 0.001.

EXERCISE 36 Questions to be Graded 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F (1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. Answer: The F value suggests there is a significant difference between the results of the control and treatment groups. The P-value of 0.005 is < the alpha of 0.05.This suggest that the groups are significantly
