Mistake on CFAI site or am I wrong?

CFA Level I Quant
#1

The annual returns for three portfolios are shown in the following table. Portfolios P and R were created in 2009, Portfolio Q in 2010.

**Annual Portfolio Returns (%)**2009 2010 2011 2012 2013 Portfolio R 1.0 –1.0 4.0 4.0 3.0

Q. The median annual return from portfolio creation to 2013 for:

a.Portfolio P is 4.5%.

b.Portfolio Q is 4.0%.

c.Portfolio R is higher than its arithmetic mean annual return.

C is correct. The median of Portfolio R is 0.8% higher than the mean for Portfolio R.

Im getting a Mean of 2.2 & Median of 4 … 4 - 2.2 = 1.8

Sorry about formatting … hope you can infer

Shouldn’t median be 3? If we assign numbers in an ascending order i.e. -1, 1, 3, 4, 4 then 3 appears to be the median
