Per recent school question and answer inquired students to say what they presume is the most important factor for a student to do if they wanted to achieve success. One that response stood out from the rest was practice. Successful people generally are not born successful; they become successful via hard work and determination. This is how you can get your goals. shown below are one of the answer and question example that you might possibly utilise to practice and develop your understanding and also give you insights that may help you to sustain your study in school.

## Question:

Which of the following is not a possible r-value? A.0.6 B.0.3 C. -1.3 D. -O.6

## Answer:

**Answer:**

Among following the value that is not possible fort a correlation coefficient is:

**Option: C**

C. -1.3

**Step-by-step explanation:**

A value greater than one (1) in any magnitude is not a possible r-value (i.e. the correlation coefficient) .

The value of r is always between -1 to +1

In statistics, the correlation coefficient measure the strength of the linear relationship between two variable ( i.e. dependent variable and independent variable) on a scatter plot.

**Hence, option: C is the correct answer.**

From the answer and question examples above, hopefully, they might be able to help the student resolve the question they had been looking for and take note of all the details declared in the answer above. You can potentially then have a discussion with your classmate and continue the school learning by studying the topic jointly.
