What is pathological gambling?

What is pathological gambling?

Pathological gambling, also known as compulsive gambling or disordered gambling, is a recognized mental disorder characterized by a pattern of continued gambling despite negative physical, psychological, and social consequences.

What is interval scale?

An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include: temperature (Farenheit), temperature (Celcius), pH, SAT score (200-800), credit score (300-850).

What is the difference between scale and interval?

The difference between interval and ratio scales comes from their ability to dip below zero. Interval scales hold no true zero and can represent values below zero. For example, you can measure temperature below 0 degrees Celsius, such as -10 degrees. A ratio scale has the same properties as interval scales.

Is annual income ratio or interval?

Ratio data has a defined zero point. Income, height, weight, annual sales, market share, product defect rates, time to repurchase, unemployment rate, and crime rate are examples of ratio data.

What type of variable is annual income?

For example, income is a variable that can be recorded on an ordinal or a ratio scale: At an ordinal level, you could create 5 income groupings and code the incomes that fall within them from 1–5.

Is annual income a continuous variable?

An annual income of a person is a discrete variable. This implies it cannot be constant, but if it is more convenient for your program, you can consider it as a continuous attribute, because there are so many meanings for it, again. The profits will often be broken up into groups of polls and other data sets.

Is salary a discrete or continuous variable?

In terms of statistics, this describes variables that assume only particular, distinct values and that are not continuous. For example, salary levels and performance classifications are discrete variables, whereas height and weight are continuous variables.

Is size continuous or discrete?

Often a measurement (continuous) scale underlies an ordinal or a whole number scale: 1. Shoe size is whole number (discrete), but the underlying measure is foot length which is measurement (continuous) data.

How do you know if data is continuous or discrete?

Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values that are measured over a specific time interval.

What is an example of continuous numerical data?

Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data. Some continuous data will change over time; the weight of a baby in its first year or the temperature in a room throughout the day.

What is the difference between a discrete and continuous graph?

A discrete function is a function with distinct and separate values. A continuous function, on the other hand, is a function that can take on any number within a certain interval. Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs.

Can a graph be neither continuous or discrete?

Graphs of discrete relations appear as dots. A relation is said to be continuous if its graph is an unbroken curve with no “holes” or “gaps.” The graph of a continuous relation is represented by a line or a curve like the one below. Note that it is possible for a relation to be neither discrete nor continuous.

What is the definition of continuous graph?

Continuous graphs are graphs that appear as one smooth curve, with no holes or gaps. Intuitively, continuous graphs are those that can be drawn without lifting a pencil.

How do you know if a function is continuous without graphing?

Your pre-calculus teacher will tell you that three things have to be true for a function to be continuous at some value c in its domain:

  1. f(c) must be defined.
  2. The limit of the function as x approaches the value c must exist.
  3. The function’s value at c and the limit as x approaches c must be the same.

Does a continuous function have to go on forever?

Let’s find the domain and range for the following problems. Because this is a linear equation we also know that it is a linear function. All lines continue forever in both directions, as indicated by the arrows. A continuous function has a value for every \begin{align*}x\end{align*}, or the domain is all real numbers.

Can a function be continuous and not differentiable?

When a function is differentiable it is also continuous. But a function can be continuous but not differentiable. For example the absolute value function is actually continuous (though not differentiable) at x=0.

What does it mean to be continuous but not differentiable?

Differentiability and continuity The absolute value function is continuous (i.e. it has no gaps). It is differentiable everywhere except at the point x = 0, where it makes a sharp turn as it crosses the y-axis. A cusp on the graph of a continuous function. At zero, the function is continuous but not differentiable.
