| List-I (Data) | List-II (Type of data) | ||
| (A) | The temperature of a city recorded every hour for one day | (I) | Univariate time series |
| (B) | The daily temperature, humidity and wind speed of a city recorded for one month | (II) | Pooled data |
| (C) | The population of each state of India in the census of 2011 | (III) | Multivariate time series |
| (D) | The population of each state of India in the censuses of 2001 and 2011 | (IV) | Cross-sectional data |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(I), (B)-(III), (C)-(IV), (D)-(II)
The type of data depends on how many variables are recorded and whether they are recorded over time or at one point of time.
(A) The temperature of a city recorded every hour for one day
This matches (I) Univariate time series: only one variable, the temperature, is recorded as it changes over time.
(B) The daily temperature, humidity and wind speed of a city recorded for one month
This matches (III) Multivariate time series: several variables are recorded together as they change over time.
(C) The population of each state of India in the census of 2011
This matches (IV) Cross-sectional data: the data for all the states are collected at the same point of time.
(D) The population of each state of India in the censuses of 2001 and 2011
This matches (II) Pooled data: cross-sectional data of the states are combined with time series data over two census years.
