Dichotomous are the simplest possible variables.The point here is that -given the sample size- thefrequency distributionof a dichotomous variable can be exactly described with a single number: if we've 100 observations on sex and 45% is male, then we know all there is to know about this va...
What is a Variable? The definition of a variable changes depending on the context. Typically, a letter represents them, and it stands in for a numerical value. In algebra, a variable represents an unknown value that you need to find. For mathematical functions and equations, you input their ...
The independent variableis the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the ex...
Example: When the wiper is at the extreme left position, resistance between the left terminal and wiper is zero, while resistance between the wiper and right terminal equals the component's full nominal resistance. 3. Classification of Variable Resistors Variable resistors can be classified based on...
In the 1940s, Stanley Smith Stevens introduced four scales of measurement: nominal, ordinal, interval, and ratio. These are still widely used today as a way to describe the characteristics of a variable. Knowing the scale of measurement for a variable is an important aspect in choosing the ri...
The invoice must be checked against the goods and sent to the Account Department. Arrangements for the payment to suppliers must be made. All these expenses accumulate into a variable cost which varies with individual orders. The smaller the number of orders, the lower is the order cost. ...
... When a programming language allows a variable of one data type to be used as if it were a value of another data type, the language is said to be weakly typed. What is type of data? Introduction to Data Types. Categorical Data (Nominal, Ordinal) Numerical Data (Discrete, Continuous...
This is sometimes also referred to as the "commuted value" of your annuity. However, I consider it very unwise to purchase an immediate annuity with the idea of taking a cash withdrawal from it. That's because the cash withdrawal amount is usually deeply discounted from the nominal value ...

To calculate APY, the formula is: APY = ( 1 + r ⁄ n ) n –1 The “r” variable is the annual interest rate in decimal form (so 5 percent would be 0.05). The “n” variable is the number of compounding periods per year. As an example, suppose you have a savings account ...
