### What is the basic tool of econometrics?

• A.

Linear regression model

• B.

Estimator

• C.

Economic history

• D.

Special regression model

A. Linear regression model
Explanation
The basic tool of econometrics is the linear regression model. Econometrics uses statistical methods to analyze economic data and the linear regression model is commonly used to estimate the relationship between variables. It allows economists to quantify and measure the impact of different factors on economic outcomes. By fitting a line to the data points, the linear regression model helps to identify the strength and direction of the relationship between the dependent and independent variables. This allows economists to make predictions and draw conclusions about economic phenomena.

### Which of these relates GDP rate to unemployment rate?

• A.

Okun's law

• B.

Bayern's law

• C.

Charlene's law

• D.

Law of demand

A. Okun's law
Explanation
Okun's law is an economic concept that relates the change in unemployment rate to the change in GDP rate. It states that for every 1% increase in the unemployment rate, there will be a 2% decrease in the GDP rate. This law suggests that there is an inverse relationship between unemployment and GDP, meaning that when unemployment is high, GDP tends to be low, and vice versa. Okun's law is used to analyze and predict the impact of changes in unemployment on the overall economy.

### Which of these is not a statistical property in econometrics?

• A.

Unbiasedness

• B.

Consistency

• C.

Accuracy

• D.

Efficiency

C. Accuracy
Explanation
Accuracy is not a statistical property in econometrics because it refers to the closeness of a measured value to the true value, which is a concept more commonly associated with measurement error or precision. In econometrics, the focus is on estimating relationships between variables and making predictions, rather than on the exactness of individual measurements. Therefore, unbiasedness, consistency, and efficiency are more relevant statistical properties in econometrics as they relate to the accuracy and reliability of the estimated parameters and predictions.

### Which of these refers to the average of economic data obtained?

• A.

Mean

• B.

Median

• C.

Mode

• D.

Regression

A. Mean
Explanation
The correct answer is Mean. The mean is a measure of central tendency that represents the average of a set of economic data. It is calculated by summing up all the values in the data set and dividing it by the total number of values. The mean provides a balanced representation of the data as it takes into account all the values in the data set.

### Which of these refers to the observation that occur most frequently in econometrics?

• A.

Mean

• B.

Mode

• C.

Variance

• D.

Standard deviation

B. Mode
Explanation
The mode refers to the observation that occurs most frequently in econometrics. It is the value that appears the most in a given set of data. Unlike the mean, which calculates the average value, or the variance and standard deviation, which measure the spread of data, the mode focuses on identifying the most common observation. It is useful in understanding the central tendency of a dataset and identifying the most frequent occurrence in order to make informed decisions or predictions.

### Which of these is mathematically derived from the standard deviation?

• A.

Variance

• B.

Mean

• C.

Median

• D.

Correlation

A. Variance
Explanation
Variance is mathematically derived from the standard deviation. It is a measure of how spread out the data points in a data set are. The standard deviation is calculated by taking the square root of the variance. Therefore, variance is directly related to the standard deviation and is derived from it.

### Which of these is concerned with the relationship between two indices?

• A.

Regression

• B.

Correlation

• C.

Median

• D.

Mean

A. Regression
Explanation
Regression is concerned with the relationship between two indices because it analyzes and models the relationship between a dependent variable and one or more independent variables. It helps to understand how changes in one variable affect the other variable. By using regression analysis, one can determine the strength and direction of the relationship between the indices and make predictions or estimate values based on this relationship.

### Which of these is unrelated to econometrics?

• A.

Control theory

• B.

System identification

• C.

System analysis

• D.

Consumer behaviour

D. Consumer behaviour
Explanation
Consumer behaviour is unrelated to econometrics because econometrics is a branch of economics that uses mathematical and statistical methods to analyze economic data and make economic forecasts. It focuses on the relationship between economic variables and does not specifically study consumer behaviour. Control theory, system identification, and system analysis, on the other hand, are all related to econometrics as they involve the study of mathematical models and statistical methods to analyze and control economic systems.

### Which of these is concerned with the relationship between demand and supply?

• A.

Equilibrium price

• B.

Control theory

• C.

Bias

• D.

System analysis

A. Equilibrium price
Explanation
Equilibrium price is concerned with the relationship between demand and supply. It refers to the price at which the quantity demanded by consumers equals the quantity supplied by producers. It is the point where the forces of supply and demand are balanced, resulting in no shortage or surplus in the market. Therefore, equilibrium price is directly related to the interaction between demand and supply in determining market prices.
