Baseball Stats: Rate and "Plus" Stats (OPS, wOBA, FIP, etc.)

SLUGGING PERCENTAGE (SLG) CORRECTION:

The scale for Slugging Percentage (SLG) looks something like this:

Poor: .310
Below Average: .360
Average: .410 +/- .15
Above Average: .450
Great: .500
Elite: .600

I mistakenly kept the scale for OBP up for SLG! Sorry about that.

This is the second video in a five-part comprehensive guide to baseball statistics. I'll update this description as needed, but the title says it all. This is a hefty video where we talk about baseball stats like:

Batting Average (AVG)
On-Base Percentage (OBP)
Slugging Percentage (SLG)
On-Base plus Slugging (OPS)
Weighted On-Base Average (wOBA)
Reference wOBA (rOBA)
Isolated Power (ISO)
Walk-to-Strikeout Rate (BB/K)
Batting Average on Balls in Play (BABIP)
Earned Run Average (ERA)
Walks + Hits Per Inning Pitched (WHIP)
Runs Allowed per 9 (RA9)
Fielding Independent Pitching (FIP)
Expected FIP (xFIP)
Strikeout Rate (K%)
Walk Rate (BB%)
Home Run Rate (HR%)
Plus Stats, such as OPS+, wRC+, FIP+, ERA+, xFIP

If you've ever wondered What Is wOBA? What is OPS? What is wRC+? This is the video for you. This is also a video for people who want to know about more classic stats. Maybe you wonder What is Batting Average? What is ERA in Baseball?

The full series will be as follows:

#1: Counting Stats & History
#2: Rate Stats and "+" Stats (you are here)
#3: Defensive Stats (non-Statcast)
#4: Statcast
#5: WAR & Related Stats (and corrections / omissions)

I hope you'll stick around for the next video in the series.
