Data Tables and Graphs
2
A data table is a good way to collect data as well as share data with others In a data table your IV goes on the left side and your DV goes on the right column(s) *this is different from graphs* Example: What’s the IV, What’s the DV? Type of RestTest 1 Test 2 Test 3 Well-rested Students959091 Tired Students757782
3
Graphs allow you to share information in a way that is easy to understand The graphs you will use most often in Biology are bar graphs, line graphs and double line graphs
4
- A TITLE that explains what is being shown on the graph - Ex: Student Test Scores A title is NOT a question! A title should be descriptive
5
EQUAL INTERVALS! Depending on your data you may count by 1,.5, 100, 10,000, etc…MUST BE EQUAL! Start with 0 and end above your last data point! For example, if your data went from 23 to 96 you would probably start with ___ and end with ____ Find your range by subtracting the lowest from highest numbers (after you decide where you want to start and end) Divide by 10 to find your intervals
6
LABELED X AND Y AXES You must tell what is being show on each axis, as well as what units where used to measure Remember the DV must be on the y axis and the IV must be on the x axis
7
Bar graphs are used when COMPARING data Each bar should be the same width Bars can touch when grouping data
8
You will use these graphs the most in Biology These graphs show change over TIME (minutes, seconds, days, years, etc.) Intervals (spaces) on both the x and y axis must be equal! Plot your data using dots, then NEATLY connect the dots to create a line
10
This kind of graph is always on the EOC! I’ve even heard rumor of three line graphs. It is just like a line graph, except you add another line showing another set of data Plot one line completely, then plot the next Your second line should have a different color, point shapes, etc. Make a key showing what each line represents
