Science 9
Midterms are in two weeks. Science 9 is on Monday, November 2nd first block of the day. The mid-term is written in the classroom. The entire space unit is on the exam and a portion of Matter. Today in class, we discussed pages 16 - 18 in the text, Properties of Matter. The set of notes from the last two days are on my Wikisite. To access them, go back to the GMCS website and hit the main page of my blog. On the left column, there is a link to my Wiki.

Math 9
Chapter 8 – SAMPLING
Page 331 in text book
People collect data because they need information. Instead of surveying the entire population, a small portion, called a sample, is studied.
A representative sample truly represents a population. It MUST:
• Reflect the population. This means all parts of the population are fairly represented.
• Ensure all members of the population have an equal chance of being selected. That is, the sample members must be chosen at random.
When we use sampling to survey a population, the sample must be random and must accurately reflect the population.
A biased sample has characteristics not typical of the population.
