A type of sample where each member of the population has an equally likely chance of being selected. The members of the sample are chosen independently of one another.

• Convenience Sample
• Random Sample

• Stratified Sample
• Cluster Sample
• Systematic Sample

A type of sample where the sample is chosen because of its proximity and accessibility to the researcher.

• Convenience Sample
• Random Sample

• Stratified Sample
• Cluster Sample
• Systematic Sample

A type of sample where the population is divided into subgroups, so that each population member is in only one subgroup. In here, the individuals are chosen randomly from each subgroup.

• Convenience Sample
• Random Sample

• Stratified Sample
• Cluster Sample
• Systematic Sample

A type of sample where the sample consists of items in a group such as a neighborhood or a household. This group may chosen at random.

• Convenience Sample
• Random Sample

• Stratified Sample
• Cluster Sample
• Systematic Sample

A type of sample where the sample is obtained using an ordered list of the population, thus selecting members systematically from the list.

• Convenience Sample
• Random Sample

• Stratified Sample
• Cluster Sample
• Systematic Sample

Data consisting of numbers representing counts or measurement.

• Discrete data

• Qualitative data
• Continuous data

• Quantitative data
