6. What is data collection? - Data collection is the process of gathering and measuring information on targeted variables in an established systematic fashion, which then enables one to answer relevant questions and evaluate outcomes. - There are two sources of data collection techniques: primary and secondary collections.

7. Primary Data Collection: -uses surveys, experiments or direct observations. Secondary Data Collection: -it may be conducted by collecting information from a diverse source of documents or electronically stored information, census and market studies. This is also referred to as “data mining”.

8. The members of Math Club elected their officers. There 4 candidates for president and members voted. This is how the members voted: Study the example of data collected and make frequency or total table and then answer the following questions.
