To find the mean, we need to add up all the populations and divide by the number of counties. 
$$(1,346,024+9,179,832+2,666,314+1,408,167+1,143,334+1,629,774+ 2,741,850+1,609,193)/8 \approx 2,715,561$$
To find the median, we need to order the populations from least to greatest and find the middle value. 
$$(1,143,334, 1,346,024, 1,408,167, 1,609,193, 1,629,774, 2,666,314, 2,741,850, 9,179,832)$$
The median is 2,715,561.
To find the mode, we need to find the value(s) that appear most frequently. There is no repeating value in this set, so there is no mode.
