SZRZ6014 A181 Sampling Strengths & Weaknesses by Nurliyana Bukhari https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses Made with Statistical Thinking en-us 2018-03-06 06:02:57 UTC 2023-08-05 02:53:58 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Pizza.png Simple Random Sampling n_bukhar https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses/wish/302810816 Strengths
  1. Everyone in the target population has an equal chance of being selected in the research
  2. For very large sample, sample represent target population & eliminate sampling bias.
  3. Easy to use, analyze and interpret results
  4. It is very easy to assess the sampling error in this method.
  5. This is suitable for data analysis which includes the use of inferential statistics.

Weaknesses
  1. Very costly (i.e., time, effort, money). For large population, it is time consuming to create a list of every individual in
  2. Cannot be employed in heterogeneous population
  3. The selection of sample becomes impossible if the units or items are widely dispersed.
  4. This method carries larger errors from the same sample size than that are found in stratified sampling.
  5. It may be impossible to contact the cases/individuals which are very widely dispersed.

1. Selvashanthini
2. Puganeswary
3. Vanaja
4. Jagathisvaran

Strengths...
  1. Sample easy to select and implement.
  2. Suitable sampling frame can be identified easily.
  3. Sample evenly spread over entire reference population.
  4. Easier to draw without mistakes.

Weaknesses
  1. Sample may be biased.
  2. Difficult to access.
  3. Sample collected may not be an accurate representation of the entire population.

1. Convenient 
2. Better than random sampling (it has some stratified sampling and random sampling criteria)
3. Economical


Weaknesses:
1. Every stage has errors (the more stages, the more probability of errors) 
2. Bias not everyone has equal chance due to unequal size)]]> 2018-11-10 08:34:49 UTC https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses/wish/302832646 1. Armeetaa Kaur https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses/wish/302832903 2. Balkis
3. Sharon

Strengths
1. Accurately reflects the population being studied.
2. We have control over the subgroup.

Weakness:
1. Cannot be used in every study.
- Several condition must be met
2. overlapping. ]]> 2018-11-10 08:38:53 UTC https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses/wish/302832903 Proportional Stratified Group https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses/wish/302833132 Group Name:
1. Nurul Jannah
2. Saiha
3. Nurul
4. Roseliza

Strengths:
1. Lesser bias because we use lesser stage.
2. It represents the population quite fairly.

Weaknesses:
1. Imbalance sampling in terms of gender.
2. The sorting of groups can be more difficult if more subgroups are taken into account.]]> 2018-11-10 08:42:01 UTC https://padlet.com/n_bukhar/SZRZ6014_A181_SamplingStrengthsWeaknesses/wish/302833132
