Question

Topic is Correlation:

you must discuss the topic, how it relates to every day life and something you learned about the topic

Answer 1

What is correlation

Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together. A positive correlation indicates the extent to which those variables increase or decrease in parallel; a negative correlation indicates the extent to which one variable increases as the other decreases.

About correlation coefficient

correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict change to the value of another. When the fluctuation of one variable reliably predicts a similar fluctuation in another variable, there’s often a tendency to think that means that the change in one causes the change in the other. However, correlation does not imply causation. There may be, for example, an unknown factor that influences both variables similarly.

Correlation relates to everyday life in the following ways -:

Positive Correlation Examples

The more time you spend running on a treadmill,

the more calories you will burn.

Taller people have larger shoe sizes and shorter people have smaller shoe sizes.

The longer your hair grows, the more shampoo you will need

.

The less time I spend marketing my business, the fewer new customers I will have

Negative Correlation

A student who has many absences has a decrease in grades.

As weather gets colder, air conditioning costs decrease.

If a train increases speed, the length of time to get to the final point decreases.

If a chicken increases in age, the amount of eggs it produces decreases.

There are many other ways in which correlation relates to our daily life the above given examples are just some of them

Something that I have learnt from correlation

The usage of correlation analysis or regression analysis depends on your data set and the objective of the study. Correlation analysis is used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two variables
