Today’s modern traffic lights are based on his original design

Work Session Unit 6 Standards/Concept Map use technology or math book to fill in the vocabulary awareness chart I can describe a relationship as increasing or decreasing, linear or nonlinear, from an equation, table or graph. I can construct and interpret scatter plots. I can describe the relationships shown in a scatter-plot (identifying patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association).

I can describe the relationships shown in a scatter-plot (identifying patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association).

Scatter Plot (foldable) A scatter plot is a graph of a collection of ordered pairs (x,y). The graph looks like a bunch of dots, but some of the graphs are a general shape or move in a general direction.

Positive Correlation (foldable) If the x-coordinates and the y- coordinates both increase, then it is POSITIVE CORRELATION. This means that both are going up, and they are related.

Positive Correlation (foldable) If you look at the age of a child and the child’s height, you will find that as the child gets older, the child gets taller. Because both are going up, it is positive correlation. Age 1 2 3 4 5 6 7 8 Height “ 25 31 34 36 40 41 47 55

Negative Correlation (foldable) If the x-coordinates and the y-coordinates have one increasing and one decreasing, then it is NEGATIVE CORRELATION. This means that 1 is going up and 1 is going down, making a downhill graph. This means the two are related as opposites.

Negative Correlation(foldable) If you look at the age of your family’s car and its value, you will find as the car gets older, the car is worth less. This is negative correlation. Age of car 1 2 3 4 5 Value $30,000 $27,000 $23,500 $18,700 $15,350

No Correlation(foldable) If there seems to be no pattern, and the points looked scattered, then it is no correlation. This means the two are not related.

No Correlation(foldable) If you look at the size shoe a baseball player wears, and their batting average, you will find that the shoe size does not make the player better or worse, then are not related.
