# Grade 3: data analysis. Create a line plot to analyze game scores.

For grants and proposals, it is also useful to have power analyses corresponding to common data analyses. We have examples of some simple power analyses below.

## In our data analysis lessons, kids learn to:

### data analysis and statistical software

The above figure depicts the fact that as the exactness of a statistical model increases, the level of improvements in decision-making increases. That's why we need statistical data analysis. Statistical data analysis arose from the need to place knowledge on a systematic evidence base. This required a study of the laws of probability, the development of measures of data properties and relationships, and so on.

### Below is an example and templates on data analysis planning.

Decision making process under uncertainty is largely based on application of statistical data analysis for probabilistic risk assessment of your decision. Managers need to understand variation for two key reasons. First, so that they can lead others to apply statistical thinking in day to day activities and secondly, to apply the concept for the purpose of continuous improvement. This course will provide you with hands-on experience to promote the use of statistical thinking and techniques to apply them to make educated decisions whenever there is variation in business data. Therefore, it is a course in statistical thinking via a data-oriented approach.

One topic I’ve been thinking about recently is extent to which data analysis is an art versus a science. In my thinking about art and science, I rely on Don Knuth’s distinction, from his 1974 lecture “Computer Programming as an Art”:What’s the point of all this? Well, I would argue that if we cannot completely automate a data analysis for a given context, then either we need to narrow the context, or we have some more statistical research to do. Thinking about how one might automate a data analysis process is a useful way to identify where are the major statistical gaps in a given area. Here, there may be some gaps in how best to automate the exploratory analyses. Whether those gaps can be filled (or more importantly, whether

*you*are interested in filling them) is not clear. But most likely it’s not a good idea to think about better ways to fit Poisson regression models.I assign group projects in many of my courses. I have noticedthat most students have very good experiences with their group projects,but a few do not. I have noticed the same mixture of results withgroup projects in workplace settings. These experiences led me towonder about the differences between people and between groups that mighthelp account for the different experiences people have with group projects. With that as my overall research question (and mindful of the need to providean example of each kind of data analysis I want to illustrate here) I posedthe following specific research questions:Whether your goal is to present your findings to the public or publish your research in a scientific journal, it is imperative that data from advanced science projects be rigorously analyzed. Without careful data analysis to back up your conclusions, the results of your scientific research won't be taken seriously by other scientists. The sections below discuss techniques, tips, and resources for thorough scientific data analysis. Although this guide will mention various data-analysis principles and statistical tests, it is not meant to be an exhaustive textbook. Instead, you're encouraged to use this guide as a means of familiarizing yourself with the general principles of data analysis. Once you're familiar with the concepts, we encourage you to continue your exploration of the topics most relevant to your science project using the references listed in the Bibliography, as well as personal resources, such as your mentor and other science and math professionals, including your teachers. We also encourage you to read our accompanying articles about the and the . When used collectively, the information in these three articles will put you on the path towards a well-thought-out, top-quality research project.
