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

ANSWER:

O According to given: sampling! o 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 + Nature and quality of the frame. * Availability of auxiliary information about units on the force. + Accuracy requirements t the need to measure accuracy are * whether requirement and me need to measure accuracy. + cost ) operational concerns is for sample size determining mining it at is statistically consider four criterias as follows: we

will 1) Margin of error: Amount of Amount of potential potential error you accept. It is "+1-" value or tolerance value you are about we want 2) confidence How confident data your typical values are 95th 3) probability ) percentage ... of people you except to respond to your Survey or compaign 4) Population – Reach / Total noot people to whom to apply Hie data. sample size calculation: Distribution of 501. >> Sample size (margin of error 1. | confidence level )? » Trie sample sample size x population ( Sample size + population) » for Sample size determining non-statistically. It is the selection of test group based on the examiner of. Judgement rather than a former statistical method. a when we are using non-statistical sampling, we don't use table , statistical percentages.

Number of records we write at is based on the our professional judgement of tim policy, firm experts carefully. os consider many different factors such as control roles. > Two types of non-statistical sampling as follows, Judgement Sampling :- when we use professional judgement to select the sample. 2) Haphazard sampling :- when we choose a sample bias. without conscious any → Research of Gnana mr. lucus prot games, at, Godco in, my charles, or francies fameue, my.proper * Research M Gnana mr charles, Dr. fransis. + Academic research in 21st century mr-lucas Academic prof.games dugoin, Dr. Godcoin, Nyametye. * Journal of environment of natural resource management, challenges in Academic Reasearch - Mr. Lucas Adiambra. 4
