Graphing Notes Part 2

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

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

Nonlinear 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.

Direct Nonlinear The line on a direct nonlinear curves upward.

Inverse Nonlinear The line on an inverse nonlinear graph slopes downward.

Reproducibility 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.

Describing 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.

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

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