  1. Mean, Median, ModeRepresenting Algebraic Data

  2. Vocabulary Review • Mean: • Median: • Mode:

  3. Example • What are the mean, median, and mode for the following: • 89, 66, 98, 75, 96, 86, 89, 78, 75, 95, 75, 74

  4. Example • How much would the sum of 6 values have to increase in order for the mean of the 6 values to increase by 3?

  5. Word Problems Involving Rate • if the data involves a ratio (fraction), it is a rate problem • find what the numerator would be if the denominator is 0 (this is the starting point) • find the rate: subtract the starting point from one of the distances, and divide by the time traveled to reach that distance • write an equation using r = rate, d = distance, t = time • check your work with another pair of values

  6. Example • What algebraic expression relates the values for x and y given by:

  7. Example • What algebraic expression relates the values for time, in seconds, and distance, in meters, in the table below?
