BASIC STAT 101

A (a)   is the entire group of individuals or elements under study.

A (a)   is a characteristic or attribute of the elements in a collection that can assume different values.

In the (a)   level of measurement, categories are only classified without any order.

The process of selecting a sample so each element has an equal chance of being included is called (a)   sampling.

In (a)   sampling, naturally occurring groups are selected randomly, and all members of selected groups are studied.

The collection of all observations for a variable is called (a)  

A (a)   survey involves asking every element in the population.

The main measurement instrument used in surveys is the (a)   .

One of the pitfalls in questionnaire design is asking (a)   questions, which cover more than one issue at a time.

In (a)   sampling, the population is divided into subgroups, and a random sample is taken from each subgroup.
