Question

The data given as 22, 27, 28, 29, 35, 37, 55 and 62 will be called as
A.A continuous series
B.A discrete series
C.An individual series
D.Time series

Answer 1

Hint: By the definition of an individual series, where the values are individual numbers and all the numbers have a frequency of 1, the given data should be called as an individual series. All the individual numbers are listed out in an individual series.

Complete step-by-step answer:
The given series is 22, 27, 28, 29, 35, 37, 55 and 62. Here 8 numbers are listed and none of them have a frequency of more than 1. Thus, by the definition, the given data will be an individual series.
In a discrete series, all the observations are listed along with their frequencies. Also all the observations may not have the same frequency.
For a continuous series, the data is divided in different classes or intervals along with the frequency of that interval. Here too the frequencies of classes may vary from one another
A time series is a series of data, which are arranged in time order. That is on the x-axis the value will indicate time in some or the other unit (second, minute, month, year, etc.). Time series is generally used to study various data which change with time. For example, the study of the stock market will have appreciable use of time series.
Hence, option (C) is the correct option.

Note: There is a slight difference between individual series and discrete series, in that individual series have data, with all having frequencies as 1, whereas the discrete series also has numbers, but the frequencies is not necessarily equal to 1, it may be more and different from one another.
