The world is full of data and it can be quite challenging to infer the knowledge based on statistical reasoning. This course aims to equip you with the skills you need to play with your data, wrangle it, and visualize it.  

Starting with data visualization, the course gets learners building ggplot2 graphs early on and then continues to reinforce important concepts graphically throughout the course. After moving through data wrangling and data importing, you’ll be introduced to modeling, which plays a prominent role, with a focus on building regression models and inference for regression. Lastly, statistical inference is presented through a computational lens with calculations done via the infer package.

By the end of this course, you’ll develop your data science toolbox, equipping yourself with tools such as data visualization, data formatting, data wrangling, and data modeling using regression.

What do we call a hypothesis test consisting of a test between two competing hypotheses?

What do we call a hypothesis test consisting of a test between two competing hypotheses?

**(True or False)** A $p$-value is the probability of obtaining a test statistic as extreme or more extreme than the observed test statistic. assuming the null hypothesis $H_0$ is true.
