E stands for "entropy," which is the opposite of an ordered pattern. Entropy is good: the bigger the E, the harder a password is to crack.
We calculate password entropy by first looking at the number of various characters that make up a password. there are 26 characters from the English alphabet. so if you had a password that was Password that would increase your list to 52 characters. Here, I have listed the total sum of all UTF-8 standard characters
 Lowercase - 26
Lower & Upper Case - 52
Alphanumeric - 36
Alphanumeric & Upper Case - 62
Common ASCII Characters - 30
Diceware Words List - 7,776
English Dictionary Words - 171,000

Password entropy is measured in bits which is how you will mathematically figure out how secure your passwords are. Below I have listed a chart that, when applied to your results will inform you how secure your password is.
Below 28 bits - Very Weak
28-35 bits - Weak
36-59 bits - Reasonable
60-127 bits - Strong
128 and Above - Very Strong
