In fairness, they might be using the median average as opposed to the mean average.

The mean average (which is what most peeople assume when the see the word “average”) is simply \$60 million divided by 572,000.

The median average would be the amount of the donation that has an equal number that are smaller and larger. In this case the 286,000th highest/lowest dontaion would be the mean average.

The median can sometimes give a more accurate picture because it is not as skewed by extreme amounts.

For example if there are 5 houses on a block worth:

200,000
225,000
250,000
300,000
1,500,000

The mean average would be \$495,000
The median average would be \$250,000

In this case the median would more accurately reflect the typical home price.

However, given that campaign donations for individuals are capped, I’d think the mean average would be a better reflection of the truth, as there aren’t any huge contributions to skew the average.

************************
mean or average = average of all values
median = midpoint between high and low values
median average = no such thing
495,000 = average (2475k/5)
850,000 = median (200k+1500k=1700k/2)

Not wanting to argue, AMPG, it’s just that the numbers you posted didn’t look right.
