8.10 Descriptive statistics: Descriptive statistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures.

Everything counts and there is no statistical punishment

 Why are these the most important things? The three things to remember about the concept of sampling that I got for the class and slides were 1. Sampling is a Process. Statistics is concerned with taking data and turning it into useful and consumable information. Transforming data into information that starts with summary statistics by means, median, range, and standard deviation.  2. Samples are the Results of the process. The ability to compare things to another and have basic knowledge and understanding

Chapter 1 problems Problem 1.1. Theoretical explanation: The three first steps of experiment design can be summarized as: 1. Recognition of the problem and problem statement: During this step, the objective is that of identifying the research question you try to solve through the experiment design. Note that failing to identify the correct research question will imply that you solve a complete different problem, or reach no solution at all. 2. Selection of the response variable: Once you have identified

After reading Chapter 1.1, I've learned that statistics involves the collection, organization, analyzation, and interpretation of data. Statistics is divided into two types, Descriptive statistics and Inferential statistics, and both are needed when using data.

Baseball statistics have gotten increasingly complicated over time. Once upon a time, people primarily used counting stats like RBIs, home runs and stolen bases. Some of the most complicated statistics were stats like batting average, fielding percentage and ERA basically requiring little more math than average division. Then, there were statistics like FIP, wOBA and WAR. These are difficult to calculate but are reasonably simple to understand. A higher wOBA and WAR is better than a lower one. Now

data types with descriptive and inferential statistics. Determining the appropriate test, hypothesizing, and assessing the results creates opportunity cost for sound decisions that aid developments to most operations. Therefore, having a solid understanding to statics is very important.

Without standard deviation
