week 6

Question 1

indentify the target vs accessible population

Answer 1

target: is the group of people from whom you want to generalize your results→ an example would be menopausal women with breast cancer

Accessible: is the subgroup of the target population that can be elistically accessed→ example would be menopausal women listed in provincal breast cancer registries

Question 2

identify sample

Answer 2

is the group of individuals who where recruited to actually particiapte in the study

Question 3

• identify sampling methods

Answer 3

random: simple, systematic, stratified, cluster

non-random: convenience, quota, purposive, networ

Question 4

• describe the difference between random and non-random sampling

Answer 4

random=every person in the target population has an equal chance of being recruited

non-random: indivduals are recruited based on judgment/convience

Question 5

define and describe the random sampling methods:
1, simple random sampling

Answer 5

1. people are selected randomly from a numbered list by using a table of random # or online sample generator
   
   • requires establishment of a list of individuals from the accessible population

Question 6

define and describe the random sampling methods:
systemic random sampling

Answer 6

2. individuals are chosen from a list every xth indivual using a random start point
   
   • requires the establishment of a list of people and intervals for selection

Question 7

define and describe stratified random sampling

Answer 7

3. p
   Stratified random sampling is a method where a population is divided into subgroups (strata) based on shared characteristics. Individuals are then randomly selected from each subgroup to ensure all parts of the population are fairly represented in the sample
   
   • requires knowning the characteristcs of the population in order to make stratification criteria

Question 8

describe cluster random sampling

Answer 8

4. clusters so groups of individuals that naturally occur in the population are randomly selected instead of recruiting individuals one by one like recruiting a school, team etc.
   
   • requires a series of random groups of individuals from the population

Question 9

describe and define non-randoming sampling: convience sampling

Answer 9

are selected based on their availability, accessibility or because they are easy to reach but this doesn’t really give a representation of the target population but is convienent

Question 10

describe and define non-randoming sampling: pruposive/judgment sampling

Answer 10

people are deliberately chosen by the researcher because they have the specific characteritics of the target population and they meet all the exlusion/inclusion criteria

Question 11

describe and define non-randoming sampling: quota sampling

Answer 11

you pick people to be part of your study based on certain characteristics, like their age, gender, or where they live. You decide how many people with each characteristic you need so that your group of participants reflects the larger population you’re interested in. However, unlike some other methods, you don’t pick these people randomly. Instead, you choose them in a way that’s easiest or most convenient until you fill each “quota” or category you’ve set. like stratified by not randomly selected

Question 12

describe and define non-randoming sampling: netowrk (snowballing sampling)

Answer 12

uses referals of the orginal participant who has the same charactericts
