# Statistics - Sample Planning

Sample planning refers to a detailed outline of measurements to be taken:

**At what time**- Decide the time when a survey is to be conducted. For example, taking people views on newspaper outreach before launch of a new newspaper in the area.**On Which material**- Decide the material on which the survey is to be conducted. It could be a online poll or paper based checklist.**In what manner**- Decide the sampling methods which will be used to choose people on whom the survey is to be conducted.**By whom**- Decide the person(s) who has to collect the observations.

Sampling plans should be prepared in such a way that the result correctly represent the representative sample of interest and allows all questions to be answered.

## Steps

Following are the steps involved in sample planning.

**Identification of parameters**- Identify the attributes/ parameters to be measured. Identify the ranges, possible values and required resolution.**Choose Sampling Method**- Choose a sampling method with details like how and when samples are to be identified.**Select Sample Size**- Select an appropriate sample size to represent the population correctly. Large samples are generally proner to invalid conclusion.**Select storage formats**- Choose a data storage format in which the sampled data is to be kept.**Assign Roles**- Assign roles and responsibilities to each person involved in collecting, processing, statistically testing steps.**Verify and execute**- Sampling plan should be verifiable. Once verified, pass it to related parties to execute it.
