# An Exploration of UFC Data — Part 3-b: Preliminary Data Analysis

Descriptive statistics on the whole dataset

To understand what questions we might be able to formulate, it is helpful to take a quick glance at the dataset as a whole. Perhaps we can answer some simple questions based upon the descriptive statistics.

Many of the interesting questions revolve around how winners and losers might differ in terms of their strikes landed, takedowns, submission, and passes. Future questions, such as whether winners can be predicted can be answered after a general sense has been explored.

Using the “describe” function in the Hmisc package simplifies the process of conducting descriptive statistics on all the variables of interest in my dataset. I purposefully left out the fighters names.
