Ilustracja interaktywna przedstawia temperaturę powietrza w stopniach Celsjusza mierzoną przez 5 kolejnych dni. Pomiar temperatury został przedstawiony w formie wykresu punktowego. Tytuł wykresu to: The air temperature degrees Celsius. Na osi x: the following days oraz wartości 1, 2 , 3, 4, 5, 6. Na osi y: the temperatura degrees Celsius oraz wartości 0, 5, 10, 15, 20, 25. Temperatura w poszczególnych dniach została oznaczona numerami od 1 do 5. Numer 1 - ma współrzędne na wykresie (1, 10). Numer 2 - ma współrzędne na wykresie (2, 15). Numer 3 - ma współrzędne na wykresie (3, 10). Numer 4 - ma współrzędne na wykresie (4, 15). Numer 5 - ma współrzędne na wykresie (5, 20). Na numerach widoczne są podpisy.

Look at the graph and give the following information:

a) the value of the temperature on the second day,
b) the value of the temperature on the fifth day,
c) the days when the temperature was the lowest,
d) the days when the temperature was the highest,
e) calculate the arithmetic mean of the air temperature during these days.

After joining the points with the segments, we get the linear graphlinear graphlinear graph.

Such graphs can be seen in newspapers or on the Internet.

Task 4

An extra task:

Zosia lives in Czestochowa and her friend Jan lives in Sydney. They decided to measure the air temperature at 12 o’clock for a week and write down the results in the tabletabletable.

Zosia made the following table.

Draw two scatter plots illustrating the change of the air temperature in Czestochowa and Sydney (use two different colours).

a) Read the values of the temperature in Czestochowa and Sydney. Note the dates. What can you notice?
b) What temperature was in Sydney on the 25Indeks górny th of July?
c) What temperature was in Czestochowa on the 26Indeks górny th of July?
d) In what city was the temperature higher and by how many degrees?
e) On which day was the temperature the lowest in Czestochowa and what was its value?
f) On which day was the temperature the highest in Sydney and what was its value?g) For how many days did the temperature in Sydney remain the same?

Remember:

  • The data can be read using the scatter plotscatter plotscatter plot or the linear chart.

  • We can draw a scatter plot on the basis of the tabletabletable.
