Probability techniques, such as simple random, stratified (sampled to meet fixed quotas based on previously defined variables), systematic random or cluster sampling methods underlie quantitative methodologies, allowing statistical inferences based on generalisations from the sample to a wider population to be drawn [ 33- 35].
The sample is generated through stratified random sampling within this panel, with quotas based on gender and age to ensure the final sample is representative of each country's adult (18 years of age and older) population.
A nationally representative sample was achieved using set quotas based on the age, gender and regional distribution within New Zealand.
Quota sampling was used to ensure the demographic representation of the general population, with quotas based on age, sex, and residential district in Hong Kong (Rubin et al. 2009).
Proportional quota sampling was used to ensure that respondents were demographically representative of the general population, with quotas based on age, sex, work status, region, and social grade.
Proportional quota sampling was used to ensure that respondents were demographically representative of the general population with quotas based on age, sex, work status, region and social class.
A proportionate distribution of participants was ensured by allocating proportional quotas based on school response rate.
Quota-based sampling was used to reach a target sample of 800 with equal proportions of non-Hispanic black and white women.
In each region, we took 50 samples according to nonproportional quota sampling based on type of setting and size of hospitality venue (< 100 m/> 100 m).
The DCE surveys will be administered using either a web-based survey or a paper survey with quota sampling based on dialysis modality, age, sex and ethnicity to recruit a respondent sample broadly representative of the New Zealand dialysis population.
The DCE survey will be conducted using a web-based questionnaire administered to a respondent sample broadly representative of the Australian public, recruited using quota sampling based on age and gender.
