mathematical analysis of baseball records and data. Sabermetrics uses its own unique statistical categories to measure player performance instead of the more orthodox categories including: runs batted in (RBI)‚ home runs (HR)‚ and wins (W) for a pitcher. The theory behind sabermetrics produces data using complex formulas to determine the value of a player for the team as a whole rather than what his own individual end-of-season statistical line indicates. By far‚ baseball has both the longest seasons

RESEARCH METHODOLOGY LESSON 20: PRINCIPLE OF HYPOTHESIS TESTING So far we have talked about estimating a confidence interval along with the probability (the confidence level) that the true population statistic lies within this interval under repeated sampling. We now examine the principles of statistical inference to hypotheses testing. By the end of this chapter you should be able to • Understand what is hypothesis testing • Examine issues relating to the determination of level of How is this

Create a Consistent Stance One of the most important things to teach young hitters is that they need to be consistent with their stance and their batting routine. Whether it is during a game or at practice‚ your player’s stance and swing should be nearly identical each time they step into the batter’s box. While not every baseball player will use the same stance‚ there are some key points that should be addressed to create a reliable and effective swing. • Proper balance • Location of hands and
