2. Keys to Good Graphs Include an appropriate title Label the axes
Make sure axes are scaled appropriately
Use a graph that is appropriate for the data
Keep it simple

3. Categorical Variable Data Sets
Pie Charts show categories as slices of a whole
Bar Charts show the distribution of a categorical variable

4. Making a Pie Chart or Bar Chart in Excel is nice and easy!
Type the categories into a column
Type the counts in the column next to the categories
Select both columns and insert the appropriate chart
Make sure your chart title and axes labels are appropriate

5. Time Series Often data is gathered over intervals of time
Ex: A record of the average pH of North Leigh Creek by year
Time will be on the x-axis (independent)
Input time data into a column
Input measured value into column next to time data
Select columns and insert chart
Label axes and chart appropriately
