Here, the horizontal axis represents the year and the vertical axis represents the population of dodos in thousands.

Approximately the population of dodos in 1990 was 30 thousand.

The mean population of dodos in thousands between 1975 and 1995
$=$ (sum of population corresponding to each year)/(Total number of years)

$=$ (50+40+35+30+10)/5
$=$ 165/5
$=$ 33 thousand dodos
