In this assignment, I will be explaining the limitations of marketing research used to contribute to the development of Waitrose´s marketing plans.

Sampling is the statistical method of obtaining representative data or observations from a group of people that is assumed will match the total populations by organizations. The total population is necessarily everyone in the country, but rather anyone who might be interested in buying the product.

There are some types of sampling and they are

Random

Quota

Stratified

Systematic

Cluster

Random sampling is the basic sampling technique where an organization selects a sample for study from a larger group (a population). Everyone is chosen entirely by chance and each member of the population has an equal chance of being included in the sample.

Quota sampling is the sampling method of gathering representative data from a group. This sampling requires that representative individuals are chosen out of a specific subgroup

Stratified sampling is a type of sampling method in which the total population is divided into smaller groups or strata to complete the sampling process

Systematic sampling is the method of choosing a random sample from among a larger population. The process of systematic sampling typically involves first selecting a fixed starting point in the larger population and then obtaining subsequent observations by using a constant interval between samples taken
