This lesson, led by Mrs. Apia, focuses on understanding the difference between populations and samples, and how to generalize findings from a sample to a population. It covers key vocabulary, exercises on data collection, and the importance of using samples. The lesson also explains the concepts of sample statistics and population characteristics, providing practical examples and exercises to reinforce learning.

• The history of statistics

• The future trends in data collection

• A specific subset of the population

• The entire population

What is the significance of determining whether data is from a population or a sample?

• It helps in understanding the scope of the data

• It affects the taste of the data

• It determines the color of the data
