Question

Choose a population that you would plan to sample or survey. Your discussion board thread title should be "Sampling from ______". Some ideas for populations to take a sample from:

Mesa students

San Diego community college students

All San Diego college students

Adults in San Diego

Starbucks customers

Your choice!

Describe an perfect scenario sampling method: Describe in your own words one of the sampling methods learned in class and how it could be applied to your population - in this case, you can assume you will have access to things like a list of everyone living in San Diego.

Describe a realistic sampling method. Being that you don't actually have a list of all San Diego residents (or similar for your population), how would YOU go about trying to get a representative sample? No need to use any fancy terms or definitions here, just describe how you'd collect data from 100 people for your sample.

What are some limitations that will arise with your realistic scenario? Are there groups that might be left out?

Answer all of this in Approximately 150-200 words in length and well-written.

Answer 1

Answer:

"sampling from Starbucks Customer ".

One of the reasonable testing technique is stratified sampling.

In stratified inspecting we first separate the number of inhabitants in N components in H gatherings (state).

These gatherings are known as strata.

From every stratum,

once in a while called a stratum.

we draw an irregular example by straightforward arbitrary testing strategy.

Gatherings are separated so that information in a gathering is homogeneous and two gatherings are heterogeneous.

At that point we study just the subset gotten by representative example.

In Starbucks information of size 100, assume we need to realize which is the most well known Coffee. First we will partition our information based on sex, age, visiting hours, occupation(or their working hours). Draw test of size 10 from each gathering . We have a subset of 40, comprising a wide range of clients. Information can be as poll.

limitations:

(a) Covering will be an issue.

(b) It is possible that at a client falls into numerous gatherings. All things considered we need to pick in which gathering that client has a place.

(c) In the event that we are gathering the information on a specific day (state weekday) there may be the plausibility we forget about those clients who visit just on the ends of the week. This may change our outcomes.
