Slide1Graphing NotesPart 2

Slide2Patterns• When you graph data, you can identify what the pattern or trend  of the data is.

Slide3Linear Graph• A  linear graph  is a graph with a straight line. • This line shows the relationship between the x- axis and y-axis.

Slide4Nonlinear Graph• A  nonlinear graph  is any graph that does not use a straight line. • Sometimes the relationship between the x-axis and y-axis is shown with a curved line.

Slide5Direct Nonlinear• The line on a direct nonlinear curves upward.

Slide6Inverse Nonlinear• The line on an inverse nonlinear graph slopes downward.

Slide7Reproducibility of Data• Scientist want their results to be able to be reproduced or  repeated . • If the data is not reproducible, then the results are  NOT accepted as true .

Slide8Describing a Set of Data• MEAN:   This is the average of the data collected of the dependent variable. • MEDIAN:   This is the value of the data point in the middle. • MODE:    This is the number that appears most often.

Slide9Slope of a Line• Slope  is the degree of slant of a line.

Slide10Calculating the Slope• Rise  = the vertical change • Run  = the horizontal change. • Slope  is calculated by dividing rise by run.  5/7 = .7
