Instructions
Find and select a graph or table of data (e.g., in a newspaper, magazine, webpage, other source) that has some count of some number of things or events, across years, or across months, weeks, or days. An example might be the number of cases of autism per year for some state. The data do not need to be about behavior per se, just so long as you can obtain some frequency count across some standard calendar time span. You should check with your instructor to see if you have an applicable dataset. For these data, select and obtain the appropriate chart. Use your imagination and find some interesting, fun, or unusual data, but use real data only!
Next, rechart these data onto the appropriate, assigned behavior chart (the name of the unit is the chart you need to be creating). Be sure to fill in all the available blanks on the chart, and be sure to include both the reference source in APA format to the original graph or data, and include a copy of the original graph or data (copied for educational purposes only under Fair Use). Next, attach a brief 1 to 2 page write-up about the data, indicating what, if any, differences show up from recharting, and then state your evaluation of the quality of the data source, and what inferences that you can make from the data. To infer something requires that you look at the data and notice levels, trends, and variability as well as any outliers or anomalies.
One objective for this project is for you to observe that the same dataset can be charted and viewed in a couple of different ways. No one method is necessarily “better” than another. But you should realize what a particular “view” of charted data will and will not tell you. Another objective is to add to your charting skills: You can, on your own, rechart frequency data so as to determine standard celerations over time. You may notice that by doing so that you can sometimes draw different conclusions from what the original authors drew. Or you may notice trends or changes that perhaps they did not see. A third objective is to continue to observe how events change and relate to one another across real time.

Sometimes there might be a “de facto” phase change (not official or necessarily planned). Are there any abrupt changes or gaps in the data set that could indicate a possible phase change? If so, note that on the chart.

This criterion is linked to a Learning OutcomeState some inferences about the data: (1) describe the overall and/or most-recent change trend(s), (2) describe the bounce (variability) to the data (and note whether the variability increased or decreased over time), (3) note any frequency changes including outliers, and (4) any possible effects of events (independent variables) on the frequency or change to frequency (the dependent variables). Note, please pay particular attention to this section of your paper, because it is important that you be able to look at a chart or graph and be able to “read” it and then to draw inferences and conclusions from it. (This point addresses a skill required for Research Methods.)
