Test: Time Series Analysis - Question 1

### In the measurement of the secular trend, the moving averages:

Detailed Solution for Test: Time Series Analysis - Question 1

Moving averages are used to smooth out the fluctuations or noise in a time series, making it easier to identify the underlying trend.

Test: Time Series Analysis - Question 2

### Prosperity, Recession, and depression in a business is an example of:

Detailed Solution for Test: Time Series Analysis - Question 2

Prosperity, recession, and depression in a business represent the cyclical trends in the business cycle. These are longer-term economic fluctuations that repeat over time and are characterized by periods of growth (prosperity), decline (recession), and severe decline (depression).

Test: Time Series Analysis - Question 3

### A set of observations recorded at an equal interval of time is called:

Detailed Solution for Test: Time Series Analysis - Question 3

A set of observations recorded at regular time intervals is referred to as time series data. Time series data is commonly used in various fields to analyze trends and patterns over time.

Test: Time Series Analysis - Question 4

The best-fitted trend line is one for which the sum of squares of residuals or errors is:

Detailed Solution for Test: Time Series Analysis - Question 4

The best-fitted trend line is the one for which the sum of squares of residuals or errors is minimized. This is because a lower sum of squares of residuals indicates a better fit of the trend line to the data.

Test: Time Series Analysis - Question 5

The graph of time series is called:

Detailed Solution for Test: Time Series Analysis - Question 5

The graph of a time series is often represented as a histogram, showing the distribution of data points over time.

Test: Time Series Analysis - Question 6
An orderly set of data arranged in accordance with their time of occurrence is called:
Detailed Solution for Test: Time Series Analysis - Question 6
A time series is a sequence of data points ordered chronologically. It represents the values of a variable at different points in time. In this context, "time series" is commonly referred to as a dataset or collection of data where each data point corresponds to a specific time or period. Therefore, the correct answer is Option D.
Test: Time Series Analysis - Question 7
A time series consists of:
Detailed Solution for Test: Time Series Analysis - Question 7
A time series typically consists of various components, including short-term variations, long-term variations, and irregular variations.

Short-term variations represent fluctuations that occur over a short period, often due to seasonality or other periodic effects.
Long-term variations indicate trends that evolve over an extended period, reflecting underlying growth or decline.
Irregular variations are unpredictable and irregular movements in the data.
So, all of these components are part of a typical time series. Therefore, the correct answer is Option D.
Test: Time Series Analysis - Question 8

The graph of time series is called:

Detailed Solution for Test: Time Series Analysis - Question 8

The graph of a time series is called a "Historigram." It is a graphical representation commonly used to visualize time series data. Therefore, option C is the correct answer.

Test: Time Series Analysis - Question 9

Secular trend can be measured by:

Detailed Solution for Test: Time Series Analysis - Question 9

Secular trend can be measured by four methods. These methods include various statistical techniques used to analyze long-term trends in time series data. Therefore, option C is the correct answer.

Test: Time Series Analysis - Question 10

The secular trend is measured by the method of semi-averages when:

Detailed Solution for Test: Time Series Analysis - Question 10

The secular trend is measured by the method of semi-averages when the trend is linear. This method is particularly suitable when the underlying trend follows a linear pattern. Therefore, option B is the correct answer.
