# GRAPHING AND ANALYZING SCIENTIFIC DATA ANSWER KEY 2 Objectives I will learn around different ways to graphically recurrent data.

You watching: Graphing and analyzing scientific data answer key

I will certainly additionally learn exactly how to analyze these graphs for scientific data. I will certainly display that I have the right to graphically reexisting information by constructing my very own graphs and also using these graphs to analyze a set of offered information. 3 Types of Graphs Pie/Circle Graphs Bar Graphs Line GraphsUsed to present components of a totality. Bar Graphs Used to compare amounts Line Graphs Used to display the adjust of one item of indevelopment as it relates to one more readjust. 4 Parts of a Graph Title Independent Variable Dependent Variable ScalesSummarizes indevelopment bing represented in ANY graph. Independent Variable Variable controlled by the experimenter. Placed on X axis. Dependent Variable Variable directly impacted by independent variable.

Placed on Y axis. Scales Tells you wbelow to plot data points. Legfinish Describes the graph’s data. 5 Variables any type of item, aspect, or problem that deserve to be managed or readjusted trying to find a reason and effect partnership 6 So then… x is the … y is the… m and b are… With Each Other they show a…Independent variable Dependent variable Constants Relationship 7 y=mx+b Are there any kind of limitations on what x have the right to be?What determines the worth of y? What happens as soon as I plug x right into that equation? Do m and b change? What is the outcome if I plug several worths for x into that equation? 8 Average, Median, Mode Average Mean ModeDetermined by adding all the numbers in a documents set together and also then separating by the number of worths. EX: = 12/3 = 4 Average Middle number in a collection of information. If there is an also set of numbers in the data, then take the average of the 2 middle numbers. EX: 2, 3, 4, 8, 12, 16, 20 median = 8 EX: 3, 5, 8, 11, 17, 19, 27, 30 median is = 28/2 Setting The number that occurs a lot of often in a data set. EX: 3, 4, 6, 6, 7, 9, 9, 9, 12, 12, 15 mode = 9 9 Extrapolate & Interpolate 10 What would you expect pay for 30 Kg?Interpreting data Extrapolate: extending the graph, along the exact same slope, above or below measured information. What would certainly you suppose pay for 30 Kg? 11 Interpreting data Interpolate: predicting information between two measured points on the graph
