The daily minimum temperatures in degrees Ce1siu& 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.
उत्तर
Since the first class is –19.9 to –15
Therefore, the frequency distribution in which the lower limit is included and upper limit excluded is:
| Temperature | Tally marks | Frequency |
| -19⋅9 to -15 | || | 2 |
| -15 to 10⋅1 | ||| |||| | 7 |
| -10⋅1 to -5⋅2 | ||||| | 5 |
| -5⋅2 to -0⋅3 | |||| | 4 |
| -0⋅3 to -4⋅6 | ||||| ||||| ||||| || | 17 |
| Total | 35 |
