Hey I need help please. If a correlation coefficient is -0.9 what can you say about the data. Also this is a separate question but what does it mean for 2 sets of data to be positively correlated.

Answers

Answer 1

Answer:

Step-by-step explanation:

A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.                          Pearson’s correlation coefficient returns a value between -1 and 1. The interpretation of the correlation coefficient is as under:

If the correlation coefficient is -1, it indicates a strong negative relationship. It implies a perfect negative relationship between the variables.

If the correlation coefficient is 0, it indicates no relationship.

If the correlation coefficient is 1, it indicates a strong positive relationship. It implies a perfect positive relationship between the variables.

A higher absolute value of the correlation coefficient indicates a stronger relationship between variables. Thus, a correlation coefficient of 0.78 indicates a stronger positive correlation as compared to a value of say 0.36. Similarly, a correlation coefficient of -0.87 indicates a stronger negative correlation as compared to a correlation coefficient of say -0.40.

Correlation Values

In other words, if the value is in the positive range, then it shows that the relationship between variables is correlated positively, and both the values decrease or increase together. On the other hand, if the value is in the negative range, then it shows that the relationship between variables is correlated negatively, and both the values will go in the opposite direction.

You know that multiplication can also be expressed as repeated addition. Why is it more difficult to use repeated addition when multiplying two mixed numbers than it is to use repeated addition when you are multiplying a mixed number by a whole number?

Answers

Answer:Let's start with the underlying fact. Multiplication simply is not repeated addition, and telling young pupils it is inevitably leads to problems when they subsequently learn that it is not. Multiplication of natural numbers certainly gives the same result as repeated addition, but that does not make it the same.

The solution of the equation 9² + 12² = c² will be 15 and negative 15.

What is the solution to the equation?

A designation of amounts to the unknown parameters that establish the equals in the formula is referred to as a result.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The equation is given below.

9² + 12² = c²

Simplify the equation, then the value of the variable c will be

c² = 81 + 144

c² = 225

c = ±√225

c = ±√(15)²

c = ± 15

Thus, the solution of the equation 9² + 12² = c² will be 15 and negative 15.
