Unfortunately, someone made a typo, typing temperature three meters from the south wall of equal thousand degrees - because of this whole schedule squeezed horizontally and differences of temperatures at the southern wall become invisible. The only thing we can do now is try to re-build the graph on the results of questionnaires, and the future to understand how important it is just to make the data before publication.
Is there a relationship between the temperature of air at noon on latitude?
Look at the map results. First state, which means each point. Let's see what number is on the point - this number is the latitude where the temperature was measured. It is clear that apart from latitude 50 degrees and 55 degrees latitude (these numbers are marked on the graph), there are at latitude 51, 52, 53 and 54 degrees, which is simply not marked, and even these lines are separated by an arc of one degree can be divided into minute and second share.
Using the graph, we can roughly estimate the geographic latitude, and to learn it more precisely, we have to look into the profile of the research team.
So, we have learned that the point on the horizontal axis of the graph indicates the geographical latitude of where the measurements.
Now let's see what number is on the same horizontal line with the chosen point - this number corresponds to the air temperature.
What information can we learn from the graph? We see that at midday temperature in the shade falls in the range from minus five to plus five degrees Celsius in points from the forty-fifth to the seventieth latitude.
At the same time, at the latitude of fifty-five to fifty-eight degrees temperature in different places was from ten to plus minus thirty degrees.
Can we now say that the south always warmer than the north?
