Study Guide Chp. 3 Assessment

1. Measures of Central Tendency
     ---Mean, Median, Mode, & Range are all ways to measure/describe/analyze a set of data
     ---Mean: Average // Median: Middle # // Mode: # that appears most often // Range: Highest - lowest

2. Formulas
    ---To solve a formula, simply plug in what you know (the numbers you are given) and solve for what you don't know (the unknown variable).
 
3. Solving Equations with Decimals
     ---Solve these the same way we solve equations with whole numbers - perform the inverse operation to solve for the variable.
     ---Remember to line up the decimals if you’re adding or subtracting, and NOT to line up the decimals  if multiplying or dividing.
   ---Don’t forget your integer rules!!! Review adding and subtracting with negatives!
