TITLE: How to Make & Use Tables & Graphs
Remember: Use 4 colors and make them mean something!!!!

What is the purpose of a data table?What are the 3 key parts of a data
table? What is the purpose of a graph? Describe two types of common
graphsHow do I make a graph?

Data table is used to: Collect & record data during an
experiment Keep track of experimental trials
![Page 5: Tables & Graphs Cornell Notes IAN Page 17](https://reader034.vdocument.in/reader034/viewer/2022051417/56814dc7550346895dbb1be5/html5/thumbnails/5.jpg)
Title Tells purpose of experiment Mentions both the I.V. & D.V.
Columns Left usually used to record the I.V. from
smallest to largest Right usually used to record D.V.▪ Multiple trials are recorded as subdivisions of the
D.V. column Averages
The values of the multiple trials are averaged & recorded in a final RIGHT column, next to the D.V. column

Graphs are used to represent your data findings
They help you analyze & communicate your data
Need graphs to help report your results

Line Graph Used when I.V. is a quantitative
(involves numbers) measurement▪ Examples: height, amounts, time, etc.
Bar Graph Used when I.V. is qualitative (doesn’t
involve numbers) or categorical.▪ Examples: days of the week, colors, types,
brand names, etc.

Clearly label your title, x-axis, and y-axis Include units and/or names
Ex: cm, seconds, brands, types, etc. Remember to graph on the correct axes
I.V. goes on the x-axis D.V. goes on the y-axis

What is the relationship between the distance below the surface and the number of fossils collected? The students collected three buckets at each location. At 80 cm below there were 0, 0, and 1 fossil; 140 cm had 2, 3, and o fossils, 200 cm had 8, 10 and 7 fossils, 260 cm had 15, 16, and 16 fossils; and 320 cm had 32, 30, and 35 fossils.

Find the question and write it down where you
plan to make your data table

Now, draw the number of columns you think you will need and fill in the data where you
think it belongs. Remember to include enough columns for multiple trials & averages
(hint: You will use 5 columns?)
