If you have an SD of 35 for an average of 1362 you have no idea about whether the last digit should be a 2. That means either you do state an error interval or you round to 1360.

If individual datapoints have an SD of 35, and you have 20000 datapoints, then the SD of studies like this is 35/sqrt(20000)≈0.24. So giving a one's digit for the average is perfectly reasonable.

(Assuming the sample is unbiased.)

According to the paper the total mean brain size for males is 1,427 while for females it's 1,272. Given around half women and half men the SD per point should be higher than 35.
