Goal – To create simple visual representation of data

Overview

• Setting up a data fileo Transferring data from collected rubrics to databaseo Coding the data from the rubrico Handling multiple reviewers

• Calculate percentageso Creating numbers to report

• Creating Charts

Transferring Data From Rubric…

To A Data File.

Coding the Rubric Data

• Four possible ratings on each learning outcomeo Not reflected 0o Minimal 1o Proficient 2o Advanced 3

Setting up columns and rows in Excel

Row = one student, Column = learning outcome

Handling Multiple Reviewers

• If there are multiple reviewers, guidelines must be created to reconcile different scores and reach a consensus.

Calculating Frequency Percentage

• Enumerate all possible answers• Create a new column next to

your original column• Highlight original column, go

to “Data” tab, click on “advanced” in the “Sort & Filter” Section.

• Select “Copy to another location” and “unique records only”.

• Copy to: click on selection box (see red circle) and then highlight the cells where you want the data to appear.

Calculating Frequency Percentage

• In next column, type “COUNTIF(“ and the select all of the cells in the original variable.

• The cell numbers will appear in the formula “COUNTIF(M2:M61”.

• Continue by typing a “,” and then select next column of numbers enumerating the different possible outcomes “COUNTIF(M2:M61,N2:N9)”

Calculating Frequency Percentage

• Copy and paste the finished cell to the rest of the value.

• Calculating percentages for each category is now possible.

Creating Charts• Highlight numbers in chart. • Go to the “Insert” tab and then

click on the down arrow near the pie option (see picture).

• A drop down box of pie options will appear. Pick one.

• Chart options can be changed under the “Design” tab, “Chart Layouts.” Clicking on the option circled in red will insert raw numbers and percentages into the pie chart.

Charts

Population and Sample Size

• For programs under 1000 students, you need to collect data from 30% of your total population size. o Please remember small populations are volatile and

small increases in sample size produces large gains in accuracy.
