Set Up an Equation To set up equations, you need to know how to:

• Add, subtract, multiply and divide (see above).
• Create an exponent: use the symbol ^ which is shift 6, e.g., 6^2 means 6*6.
• Write scientific notation: just add E and the exponent e.g., 2E3 means 2000.
• Write functions: SQRT( ) for square root, COS( ) for cosine, etc.

Bin Data

Set up bins: Figure out the first and last value of your data range and the size bin you want to use. See histogram help Make a new column of the bins: Write the first bin number. Use Edit, Fill, Series to count by 10s (or whatever you bins size is) until you get to the last bin number. Find frequency: Choose Tools, Data Analysis, Histogram. If you do not see Data Analysis under tools, your version of Excel probably needs an add-on that includes this option. Check with your teacher. For Input Range, click, highlight, and drag the values in the column that has the data you want to bin. The box should read something like this: $K$2:$K$1000 (depending on number of data cells). For Bin Range, do the same except use the bin values. The box should read something like this: $M$2:$M$52 (depending on how many bins you chose). Click on New Worksheet, OK. You should see a new page open up with two columns similar to the table on the right.

Bin Frequency 20 3 22 13     120 2
