## Overview

In this first part of a two part course, we’ll walk through the basics of statistical thinking – starting with an interesting question. Then, we’ll learn the correct statistical tool to help answer our question of interest – using R and hands-on Labs. Finally, we’ll learn how to interpret our findings and develop a meaningful conclusion.

This course will consist of:

• Instructional videos for statistical concepts broken down into manageable topics
• Weekly tutorial videos for using R Scaffolded learning with Pre-Labs (using R), followed by Labs where we will answer specific questions using real-world datasets
• Weekly wrap-up questions challenging both topic and application knowledge

We will cover basic Descriptive Statistics – learning about visualizing and summarizing data, followed by a “Modeling” investigation where we’ll learn about linear, exponential, and logistic functions. We will learn how to interpret and use those functions with basic Pre-Calculus. These two “units” will set the learner up nicely for the second part of the course: Inferential Statistics with a multiple regression cap.

Both parts of the course are intended to cover the same material as a typical introductory undergraduate statistics course, with an added twist of modeling. This course is also intentionally devised to be sequential, with each new piece building on the previous topics. Once completed, students should feel comfortable using basic statistical techniques to answer their own questions about their own data, using a widely available statistical software package (R).

With these new skills, learners will leave the course with the ability to use basic statistical techniques to answer their own questions about their own data, using a widely available statistical software package (R). Learners from all walks of life can use this course to better understand their data, to make valuable informed decisions.

Join us in learning how to look at the world around us. What are the questions? How can we answer them? And what do those answers tell us about the world we live in?

I completed this course under the Audit track, even though I didn't bother with a certificate.

This is an excellent course. It teaches not only statistics in a clear, easily understood manner, but also cultivates in the student a structured and methodical way to tackle statistical research questions.

The lecture videos and R tutorial videos are well presented and delivered. You can also download PDF transcripts of the R tutorials, which is handy for copying the commands into RStudio.

I like especially the Pre-Lab and Lab exercises. R scripts are provided…

This course is a great start to learn both statistics and the basics of R. There are different types of material for different types of learners (course videos, downloadable reading material, tutorial videos) although it is better to use them all while learning as they complement each other. If you are a beginner, I do not recommend flying through the course. Spend the time and effort to read and re-read the material before attempting the assignments. I found it more profitable when I made sure I had understood all details of the material. Otherwise, the assignments became more challenging the…

This course ended in Aug 2017. With that said, the prelab and lab units no longer function to provide answers to double check your understanding so what's the point with continuing with the course. I was taking this due to the basic understanding that I'll need some statistic background with R and Python as an aspiring data scientist. This course was highly recommended as the choice class to take as the top pick from Class-Central.

Unfortunately, someone forgot to tell them that this course is not worth the value without the videos. I'm sure it was a great course, but with all that time and effort, I guess its no longer worth it to maintain courses that can't provide a university with monetary value.
