# When a researcher observes or measures two or more variables to find relations without directly manipulating or implying causal relationship he or she is conducting?

## When a researcher observes or measures two or more variables to find relations without directly manipulating or implying causal relationship he or she is conducting?

Correlational research involves measuring two variables and assessing the relationship between them, with no manipulation of an independent variable. Correlation does not imply causation.

## When a researcher observes or measures two or more variables?

Correlational research is a type of research method that involves observing two variables in order to establish a statistically corresponding relationship between them.

## Which research method investigates & clarifies relationships between 2 or more variables?

Relational or Correlational Research A study that investigates the connection between two or more variables is considered relational research. The variables that are compared are generally already present in the group or population.

## Which of the following is an example of a continuous variable?

The continuous variable involves quantitative measures as it involves numbers or quantities. It is often considered as a random variable. Example: Eye color, gender, numbers of pets, age, etc.

## How do you find the continuous random variables?

Similarly, the probability density function of a continuous random variable can be obtained by differentiating the cumulative distribution. The c.d.f. can be used to find out the probability of a random variable being between two values: P(s ≤ X ≤ t) = the probability that X is between s and t.

## Can time be a discrete variable?

Discrete time views values of variables as occurring at distinct, separate “points in time”, or equivalently as being unchanged throughout each non-zero region of time (“time period”)—that is, time is viewed as a discrete variable. The number of measurements between any two time periods is finite.

## Which of the following is an example of a discrete random variable?

If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of children in a family, the Friday night attendance at a cinema, the number of patients in a doctor’s surgery, the number of defective light bulbs in a box of ten.

## Is height a discrete variable?

A discrete variable is one that cannot take on all values within the limits of the variable. A variable such as a person’s height can take on any value. Variables that can take on any value and therefore are not discrete are called continuous.

## What is the similarities and differences between continuous and discrete variable?

Discrete variables are the variables, wherein the values can be obtained by counting. On the other hand, Continuous variables are the random variables that measure something. Discrete variable assumes independent values whereas continuous variable assumes any value in a given range or continuum.
