SUMMARY

The discussion centers on the classification of sampling methods used in a survey conducted by the user, who collected data from passersby at various city locations. The user initially questioned whether their approach constituted random sampling or convenience sampling. A participant clarified that the method employed, which involved asking every third passerby, aligns more closely with pseudo-random sampling and relates to the Poisson Distribution. However, the consensus is that the sample may not be representative of the broader population due to the inherent limitations of the sampling technique.

PREREQUISITES
  • Understanding of sampling methods, specifically random and convenience sampling.
  • Familiarity with the Poisson Distribution and its application in sampling.
  • Knowledge of survey design and data collection techniques.
  • Basic statistical concepts related to representativeness and sample size.
NEXT STEPS
  • Research the differences between random sampling and convenience sampling.
  • Learn about the Poisson Distribution and its implications for sampling techniques.
  • Explore methods for increasing the representativeness of survey samples.
  • Investigate best practices for designing effective questionnaires for public surveys.
USEFUL FOR

Researchers, statisticians, and students involved in survey methodology, as well as anyone interested in understanding sampling techniques and their impact on data representativeness.

Hi, I hope you can help.

I collected my samples on the street by just asking passers by to fill in my questionnaire. I moved to 5 different locations within the city and spent 3 hours each visit 3 times a week for one month.

Is this random sampling? Or it it sill convenience sampling? Can anyone help me make it sound as good as possible! While i know this can never be representative, can argue that its more than convenience?

Cheers!
I also asked every 3rd passer by

I suppose it can be considered as pseudo-random sampling. It signifies the Poisson Distribution. I came to this conclusion since you've specified fixed intervals of time for the task.
 
It is random sampling (I never heard of convenience sampling). The main question is you method sufficient to get a representative sample of the population you are trying to sample? there is not enough information in your statement to answer that.
