The rate of return on an investment considering the effect of compounding, which is a more accurate representation of the actual return compared to the nominal rate.

The stated, or quoted interest rate, without considering the effects of compounding. Normally, this is the rate per year.

The future value of an annuity, where the payments are received at the end of each period, considering a specific interest rate and number of periods.

A series of equal payments made at regular intervals, where the payments are received at the end of each period.

The rate of increase in earnings per share (EPS) over a specific period.

Profit earned by a company per outstanding share of stock.

The estimated future price of a financial asset based on its current value and its expected rate of growth.

The amount of money that needs to be invested today to receive a specific future value, considering a specific interest rate and number of periods.

The sister of your father or mother.

The child of your uncle or aunt.

The daughter of your brother or sister.

A person's child who is not their spouse's child.

A person's sibling who is not their blood sibling.

The son of your brother or sister.

The person who is married to your child.

The person who is married to your sibling.

The variance of a random variable 'x' scaled by a constant 'b' is equal to the square of 'b' multiplied by the original variance of 'x'.

The change in variance of a random variable when it is linearly transformed, like 'y = 2x + 5', is only dependent on the coefficient of the variable 'x', not the constant term.

It is the ratio of the standard deviation to the mean, expressed as a percentage. It helps understand the variability of data relative to its average.

A dataset where all values are the same has zero variability, hence its standard deviation and variance are both zero.

The harmonic mean can be calculated using the arithmetic mean and geometric mean of two numbers. It is especially useful for comparing rates or proportions.

The average of the remaining two students is 15 years. This is calculated by finding the total age of all students and subtracting the ages of the first two groups.

The probability of event A occurring given that event B has already happened.

The probability of two events happening together, calculated by multiplying the probability of the first event by the conditional probability of the second event given that the first event has occurred.

Two events are independent if the occurrence of one event does not affect the probability of the other event happening.

The probability of either of two events happening is calculated by adding the individual probabilities of each event and subtracting the probability of both events happening together.

The probability of an event happening is equal to the number of favorable outcomes divided by the total number of possible outcomes.

The probability of getting exactly two heads when tossing three coins.

A probability distribution where the skewness is zero, implying a symmetrical bell-shaped curve.

The future value of an annuity where payments are received at the end of each period, considering a specific interest rate and number of periods.

A price index used when a new commodity is added to the basket of goods used for calculating the index.

A method used to combine price indices from different periods, allowing for the creation of a continuous price index.

A price index used to adjust values for changes in the overall price level, often used to compare real values over time.

A price index that reflects the total value of goods and services in a specific period.

The process of adding a new commodity to the basket of goods used for calculating a price index.

A statistical measure that describes the strength and direction of the linear relationship between two variables.

A statistical measure that describes the strength and direction of the linear relationship between two variables, specifically focusing on their ranks.

A statistical method used to calculate the correlation coefficient based on the ranks of the data, instead of the raw values.

A statistical measure that describes the strength and direction of the linear relationship between two variables, focusing on their deviations from their means.

A statistical measure that quantifies the variability of a variable, calculated by summing squared deviations of each value from the mean, then dividing by the number of observations.

A statistical measure that quantifies the spread of a variable, calculated as the square root of the variance.

The measure of the degree to which two variables change together. It is calculated by dividing the covariance of the two variables by the product of their standard deviations.

A statistical concept that describes the tendency of two variables to change together.
