The daily minimum temperature in degrees Celsius recorded in a certain Arctic region are as follows:

-12.5, -10.8, -18.6, -8.4, -10.8, -4.2, -4.8, -6.7, -13.2, -11.8, -2.3, 1.2, 2.6, 0, 2.4, 0, 3.2, 2.7, 3.4, 0, -2.4, -2.4, 0, 3.2, 2.7, 3.4, 0, -2.4, -5.8, -8.9, -14.6, -12.3, -11.5, -7.8, -2.9.


Represent them as frequency distribution table taking -19.9 to -15 as the first class interval.

Since, first class interval is - 19.0 to 15


Frequency distribution with lower limit included an upper limit excluded is:
