Rebranding is the process of changing the corporate image of an organisation. It is a market strategy of giving a new name, symbol, or change in design for an already-established brand.

The idea behind rebranding is to create a different identity for a brand, from its competitors, in the market. There are several reasons for a company to go for rebranding.

One prominent factor is to connect with customers. Rebranding is good for the business, but at the same time it may be risky. There is always a possibility that the consumers do not like the new brand. There are two types of rebranding: Proactive rebranding is done when a company recognises that there is an opportunity to grow, innovate, tap into new businesses or customers, and to reconnect with its users.

Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.

Simple Random Sample

If for some reasons, the sample does not represent the population, the variation is called a sampling error. Random sampling is one of the simplest forms of collecting data from the total population.

Under random sampling, each member of the subset carries an equal opportunity of being chosen as a part of the sampling process.

For example, the total workforce in organisations is and to conduct a survey, a sample group of 30 employees is selected to do the survey. In this case, the population is the total number of employees in the company and the sample group of 30 employees is the sample.

Each member of the workforce has an equal opportunity of being chosen because all the employees which were chosen to be part of the survey were selected randomly. But, there is always a possibility that the group or the sample does not represent the population as a whole, in that case, any random variation is termed as a sampling error.

An unbiased random sample is important for drawing conclusions. For example when we took out the sample of 30 employees from the total population of employees, there is always a possibility that a researcher might end up picking over 25 men even if the population consists of men and women.Populations: Definition - a complete set of elements (persons or objects) that possess some common characteristic defined by the sampling criteria established by the researcher Composed of two groups - target population & accessible population Target population (universe) The entire group of people or objects to which the researcher wishes to generalize the study findings.
