• Stratafied Sampling is a random sampling technique where members of each group are randomly sampled so that each group is fairly represented ie. equal number of male and females.
• Quota sampling is when you stop sampling a certain group after a quota is reached and therefore is not random ie. stop receiving responses from men after 30 men answer.
• Convenience Sampling is when you survey anyone you find and is not random.
• A statistic is of a sample
• A parameter is of a population
• Continuous quantitative data has unlimited values.
• Discrete quantitative data has limited values.
