I think the most important takeaway from this course for me is how important data is in our daily lives and the many ways we can affect it and how it affects us. Another important takeaway has to be how the smallest mistakes can skew or drastically change a result or analysis. The course teaches you to be through in an analysis and to look for mistakes

I think the most important mistake to avoid has to be Number 3, “Start working on the database without doing a full backup first.” One may forget to backup the original data and if a mistake is made during the analysis then the data can be corrupted for good. By keeping the original one can have a backup in case a mistake is made.

I think the most important of the eight principles has to be Ask Why. This is the only way to get to the bottom of something that you can use the information for a good reason. If we don’t ask about the data then what’s the point of making the data visualization. Asking why allows the researchers to find and keep finding out more information

I think the most important takeaway from this week’s discussion has to do with the idea of bias. Usually in the cases of restaurants, the reviews are usually bad on the websites because the person felt so strongly that they decided to go and write a review.

An example of conventional can be “an apple a day keeps the doctor away.” This could be a rather simple example to put into quantitative data. Essentially one would look at those who try to eat fruits daily, versus those who do not eat regular fruits. The researcher could use medical records or hospital data to attempt to figure out the problem.
