Where to find data

As you research online for relevant articles and refine your narrative for your infographic, the best way to get data is to further look up the surveys, scientific articles, and datasets mentioned in the online articles you find. These data sources are often mentioned, referenced, and linked directly from the article. This is better than just googling something general like “Teenage sleep data.” A few things to keep in mind are: 1) what would the data look like and what should it look like for making graphs, 2) is the data reliable, unbiased, and trustworthy?, and 3) is the data relevant and does it make sense?

How to Work with Data

Data Do’s and Don’ts

Issue Do Don’t
Too much data Take a random and representative sample of 500 or so data points depending on the size of dataset. If not all the data is relevant to your investigation, you can use the sample that is relevant; if your investigation is on high school students and your data set has people of all ages, you can filter out the non-high school student ages. Don’t pick a small number of data points from a large data set. Don’t pick out data points that support your claim! That would be unethical.
