From the Rett PR:

When looking at other placebo-controlled Rett syndrome trials, ANAVEX®2-73 compares favorably in terms of absolute RSBQ improvements, with the caveat that cross trials comparisons have their limitations.

Those limitation are very important and Anavex are really a bit lame with this statement comparing a failed trial with a successful one that led to approval.

Having said that, there are some things that Anavex can and likely will want to show with more analysis that could potentially help the case for an Accelerated Approval with a confirmatory trial, but chances are not great imo.

It's been too long since I had math...

Examples on Difference between Average and Mean
Example 1: A student has gotten the following grades on his tests: 82, 93, 79, and 69. He wants a 75 or better overall. What is the minimum grade he must get on the last test in order to achieve that average?

Solution:

We need to find out the minimum grade by adding all the grades given and divide it by the number of grades. Since we don't have a score for the last test, let's use the variable 'x' to determine the average.

(82 + 93 + 79 + 69 + x)/5 = 75

We move the five to the other side and multiply 5 with 75.

82 + 93 + 79 + 69 + x = 375

323 + x = 375

x = 375 - 323

x = 52

Hence, the student needs to score at least a 52 on the last test.

Example 2: Find the mean for the following data: 45, 76, 2, 10, 33.

Solution:

The given list is 45, 76, 2, 10, 33

Mean = Sum of observations/Total number of observations

= (45 + 76 + 2 + 10 + 33)/ 5

= 166/5

= 33.2

Therefore, the mean for the following list is 33.2
