• shows the number of individuals having each value

census

• is a subset of individuals in the population from which we collect data.

• 1. collects data from every individual in the

  2. population.

• in a statistical study is the entire group of individuals we want information about.

• allows people to choose to be in the sample by responding to a general invitation.

sample

• 1. The design of a statistical study shows bias if it is very likely to underestimate or very likely to overestimate the value you want to know.

• 1. A sample survey is a study that collects data from a sample that is chosen to represent a specific population.

• is a subset of individuals in the population from which we collect data.

• 1. Convenience sampling selects individuals from the population who are easy to reach.

sample survey

• is a subset of individuals in the population from which we collect data.

• of size n is chosen in such a way that every group of n individuals in the population has an equal chance to be selected as the sample.

• allows people to choose to be in the sample by responding to a general invitation.

• involves using a chance process to determine which members of a population are included in the sample.

Random sampling

• involves using a chance process to determine which members of a population are included in the sample.

• of size n is chosen in such a way that every group of n individuals in the population has an equal chance to be selected as the sample.

• a group of individuals in the population that are located near each other.

• occurs when an individual chosen for the sample can't be contacted or refuses to participate.

simple random sample (SRS)

• selects individuals from the population who are easy to reach

• Collects data from every individual in the population

• of size n is chosen in such a way that every group of n individuals in the population has an equal chance to be selected as the sample.

Strata

• groups of individuals in a population who share characteristics thought to be associated with the variables being measured in a study.

• occurs when some members of the population are less likely to be chosen or cannot be chosen in a sample

• occurs when there is a systematic pattern of inaccurate answers to a survey question

• group of individuals in the population that are located near each other
