The table below shows yearly temperature data
for the cities of St. Louis, MO, and San
Francisco. CA. How does the climate of St.
Louis compare to the climate of San Francisco ?
City
Mean Median
Mode
Range
St. Louis
55.3 57
34, 75
50
San Francisco 56.8 56.5 49, 55, 61 15
#13
Answer:
The mean and median temperatures
show that the temperature for the two
cities are similar. Yet, the modes and
range suggest that the temperatures in
St. Louis vary more widely than in San
Francisco. So, the climate of San
Francisco is less extreme than that of
St. Louis.
