Question

Write a short report on Sampling and how a Sample Size could be determined both statistically and non-statistically The class captain Mr. Lucas Adiambra presented a paper entitled "Challenges in Academic Research” during the RCEES 2nd International Conference on Engineering in Sunyani from the 11h - 13th December, 2019. The Conference proceedings were edited by Prof. James Dugan and Dr. Godwin Nyamekye which was published as a book on January 20, 2020 by KNUST Press. The title of the book is “Academic Research in the 21" Century" and his paper can be found in pages 201 - 210. He was later joined by a friend, Mr. Charles Yambra to publish the same article in a Journal of Environment and Natural Resources Management (JENRM), the 12ch Series in the third volume, pages 234 to 241. The article was so interesting that, one of their Lecturers (Dr. Francis Fameye) encouraged them to publish the article as a chapter of a book he edited entitled "Research in Ghana” printed by Elsevier, London from pages 35 to 42. He finally met another friend (Mr. Proper Awuni) who had also worked on similar information and therefore they decided to combine the work and publish it into a book with the same title in the same year. The book was finally published by the KNUST Press in Kumasi. the information above in question two, provide the reference lists for all the scenarios.

Answer 1

solution: 1. And Page 1 According to given sampling =) It is the selection of subset of individuals from within a statistical Population to estimate characteristics of the whole population. advantages of Sampling are: * lower cost *faster data collection. factors influencing the choice for Sampling are. * Nature and quality of the frame. * Availability of auxiliary information about the force * Accuracy requirements & the need to accuracy, unirs on the measure

to measure Page 2 * Whether requirement and me need accuracy * cost / operational concerns. ;) for sample size determining it at is statistically we consider four criteria's follows: 1) Margin of esooo Amount of potential esror you will accept. It is "t/_" value or to derance value. 2) confidence - How confident you are about your data typical values are as 95% 3) probability / Percentage - % of people you except to respond to your survey or campaign.

Page-3 4) population Reach/Total no of people to whom we want to apply Hie data. Sample size calculation: Distribution of 50% -> Sample size (Margin of 20000 411 Confidence 2 level sample sizex population =) True sample- (sample size + population) =) on group based for sample size determining non- statistically. It is the selection of test the examiness & judgement rather than a former statistical method. » when we are using non-statistical sampling, we don't use table Istatistical Percentages.

Page - 4 Number of records we loot at is based on the our professional judgement & trom policy, from experts carefully. >> Consider many different factors such as control roles. =) Two types of non-statistical Sampling as follows: 1) Judgement sampling : - when we use professional judgement to select the sample. 2) Haphazard sampling : - when we choose Sample without conscious bias. without any 2.
