Answer 1

• Describe the term "sampling" and describe why marketers use sampling.

Sampling refers to the statistical process of selecting and studying the characteristics of a relatively small number of items from a relatively large population of such items. The small selection is called sample.

It is generally more expensive and time consuming process to collect data from the whole population of a market. Marketers therefore make extensive of sampling from which, through careful design and analysis, marketers can draw information about their chosen market.

• Identify situations where random sampling would be best.

Random Sampling would be best. where a sample of items is chosen randomly from a population, and each item has an equal probability of being chosen.

• When would stratified sampling be used?

Stratified sampling can be used where a researcher’s target population of interest is significantly heterogeneous,a researcher wants to observe the relationship(s) between two or more subgroups; and his  goal is to create representative samples from even the smallest, most inaccessible subgroups of the population he or she is interested in.

• Describe quota probability sampling. Describe a situation how it would be used.

Quota sampling is a non-probabilistic sampling method where we divide the survey population into mutually exclusive subgroups. These subgroups are selected with respect to certain known and thus non-random features, traits, or interests. Consider the situation where an interviewer has to survey people about a Anti-acne Cream. His population is people in a certain city between 14 and 24 years old. The interviewer might decide they want two survey subgroups — one male, and the other female — each with 100 people.

• Create a 5 question questionnaire. This can be for any product. You may want to use your marketing plan product.Identify the survey method you would use for reaching the target market and why you believe this is the best method.

Product: A flavored Anti Cavity tooth paste for children

Evaluate the prevalance of tooth decay among 1200 childrens attending a school

1.List of children attending the school.

2.Children numbered from 1 to 100

3.Sample size= 100

4.Random sampling of 100 numbers between 1 and 1200.

Survey method: Random Sampling

Random Sampling would be used because samples(children) are chosen randomly from a population, and each sample(children) has an equal probability of being chosen

Questionnaire:

What is your age?

How many times you brush your teeth in a day?

Do you have tooth decay?
