If your data graphs as a curve, the variables you have plotted have a non-linear mathematical develop or connection. Non-direct information is mathematically hard to analyze. However before, if we deserve to convert the data to a direct (straight) create we have the right to use our knowledge of right lines to learn about the physics involved in our experiment. So, if we are confronted with non-direct (curved) information then our goal is to transform the data to a linear (straight) form that deserve to be easily analyzed. This process is referred to as linearization.

Tright here are four possibilities for graph forms that we will attend to. Each form represents information that exhibits a various mathematical create.

Liclose to – Our Goal! | Over-achiever | Under-achiever | Non-conformist |

y = mx + b or y = kx |
y = x2 |
y =√x |
y = 1/x or y = 1/x2 |

File is already linear.Draw a best fit line and also calculate the slope. | Make a new calculated column withthe x-axis variable squared.(X = x2).Then plot y vs. X | Make a brand-new calculated column withthe y-axis variable squared:(Y = y2).Then plot Y vs. x | Make a new calculated column withthe x-axis variable as 1/x or 1/x2(X = 1/x or X = 1/x2).Then plot y vs. X |
