Pie, Bar, and Line

Pie charts are best used to represent _____________________PERCENTAGES (%) The whole circle equals _____________ Because of this we can say that _________________________ If we simplify this, we get _____________________ 100 % = 360 degrees 1 % = 3.6  But it also equals_____________________ = 100 % 360  360 degrees

To Make a Pie Chart, You must use a ____________ Protractor (1) Once you know your Percentages, Multiply each by the conversion factor of 3.6  /1%. For Example: Percentage of different pets owned by the 8 th graders of Franklin Regional 42% Type of PetPercentage Dog42% Cat33% Fish19% Rabbit6% 3.6  1% x =  Degrees ===  ===  === 68.4  === 21.6 

Percentage of different pets owned by the 8 th graders of Franklin Regional (2) Use your Protractor to measure out the correct number of degrees for each category. 42% own Dogs 33% own Cats 19% own Fish 6% Own Rabbits

Bar graphs are best used to represent _____________________Quantities The more the bars separate, the easier it is to read. This means you don’t have to always start from _____________________ ZERO Let’s Remake the SAME Graph, but not start at ZERO WHICH ONE IS EASIER TO TELL THE DIFFERENCE BETWEEN THE BARS?

ALWAYS Label the axes. The ___________should always be the Quantity or Amount of something Y - Axis The ___________should always be the items or Categories being counted X- Axis Black & White Photo Color JPG photo Color GIF photo Color PNG Photo Average Amount of MB used ALL Graphs MUST have a __________ Title Storage Size of Different Computer Photo File Types

Line graphs are best used to show ____________________ Continuous Change Just like the Bar graphs you don’t have to always start from _____________ on the ________________ ZEROY - Axis Let’s Remake the SAME Graph, but not start at ZERO WHICH ONE IS EASIER TO TELL THE DIFFERENCE IN THE LINE?

(1) Decide which way the paper should be (Landscape or Portrait) This can be done by finding the ____________of the __________________ and ________________________. Dependent Variables Independent Range This can be found by __________________ the _____________ from the ____________for each variable. Highest Value Lowest value Subtracting Speed (Independent) Stopping Distance (Dependent) 10 mph18 m 25 mph32 m 45 mph40 m 55 mph68 m 65 mph73 m 80 mph137 m 80 mph 10 mph - = 70 mph INDEPENDENT RANGE 137 m 18 m - = 119 m DEPENDENT RANGE

The Independent Variable always goes on the ___________ The Dependent Variable always goes on the ___________ So if the Range of the Independent Variable is Larger then paper should be __________________ BUT if the Range of the Dependent Variable is Larger then paper should be ______________________ PORTRAIT LANDSCAPE X - AXIS Y - AXIS More room for the larger range of numbers

(2) How to number the Axes? Step 1 - Count the number of _________ on each axis. Step 2 – Divide the __________ for that axis by the that number Step 3 – Your answer will most likely be a decimal. So ______________to the _______________________________. Step 4 – Start with the _____________________in your range and begin numbering your lines. LINES RANGE ROUND UP NEXT EASIEST COUNTING NUMBER LOWEST NUMBER Examples: If Answer is – Then ROUND UP and COUNT by 2 If Answer is 12.1 – Then ROUND UP and COUNT by 15 If Answer is – Then ROUND UP and COUNT by 2.5

(3) Label your Axes TWO PARTS Each Label has TWO PARTS: What (a) The Measurement Name (What was Measured) How (b) The Unit of Measurement (How it was Measured) Examples: Time (Minutes) Temperature (  C) Speed (mph)

(4) Put a Title on your Graph The Best Title for your line graph is your ____________________ Not just THIS vs. THAT Hypothesis PLOT (5) Carefully PLOT your points and connect your line (6) If it is a multiple line graph you will need to make each line a different ______________, and include a _________________. (7) Lastly, since you did all of that work, DON’T FORGET TO PUT YOUR NAME ON IT. Legend Color
