What is perfect negative linear correlation?
This means that the data points lie perfectly on a line with negative slope. For example, the points (0,4), (1,3), (2,2), (4,0) are perfectly correlated since they lie on the line y = -x + 4. It is a negative correlation since the slope of the line is -1, a negative number, or alternatively because as x rises, y falls.
What is a positive negative correlation?
Correlation determines relationship between two variables. For example changes in one variable influence another variable, we can say that there is a correlation between the two variables. For example, we can say that there exists a correlation between the number of hours spent on reading and preparation and the scores obtained in the examination. One can infer that higher the amount of time spent on preparation may result in better performance in examination leading to higher scores. Hence the above is a case of positive correlation. If an increase in independent variable leads to an increase in dependent variable, it is a case of positive correlation. On the other hand if an increase in independent variable leads to a reduction in dependent variable, it is a case of negative correlation. An example for negative correlation could be the relationship between the age advancement and resistance to diseases. As age advances, resistance to disease reduces.
What is a stronger correlation than -0.54?
The correlation coefficient ranges from 0 to ±1. The sign of the correlation coefficient shows the correlation as positive (as one increases so does the other) or negative (as one increases the other decreases). 0 represent no correlation and ±1 represents perfect correlation. The further from 0 towards ±1, the stronger the correlation, ie the greater the absolute value* of the correlation coefficient the stronger the correlation. To have a stronger correlation than -0.54 the absolute value must be greater than 0.54; ie all correlation coefficients that are less than -0.54 (eg -0.6, -0.9) and all those greater than +0.54 (eg 0.7, 0.95) are stronger correlations. Mathematically speaking, all those with a correlation coefficient r such that |r| > 0.54 *The absolute value of a number is the number ignoring its sign (ie how far it is away from 0 ignoring the direction along the number line), eg |56| = 56 |-45| = 45 |-56| = 56 Thus |-56| = |56| = 56.
What is the negative of a negative number?
The negative of a negative number is a positive number.
What is a negitaive times a positive?
A negative number times a positive number will give you a negative product.A negative number times a positive number will give you a negative product.A negative number times a positive number will give you a negative product.A negative number times a positive number will give you a negative product.
Is the age of pets in a home and the number of pets in that home a positive negative or no correlation?
no correlation.
What is a real life classroom example of negative correlation?
There would be a negative correlation in the classroom, of a student's grades, with the number of days absent from class.
Is there a positive correlation a negative correlation or no correlation between daily newspaper circution and the number of television sets in homes?
I would assume a negative correlation. More TV sets per home = less newspaper circulation.
Is this positive or negative correlaton the number of pages in a book and the number of copies the book sells?
In my opinion, it is neither positive or negating correlation. The answer is no correlation.
Is the number of weeks a film has been out and total attendance a positive negative or no correlation?
In general, as the number of weeks since release increases, total cumulative attendance increases - this would be a positive correlation. However, as the number of weeks since release increases, the total weekly attendance tends to decrease - a negative correlation.
What is a Correlation example in real life?
Positive Correlation- Age - Amount of medical conditions Negative Correlation- Television Watching- Grades No Correlation- Height of a person- Number of shoes they own Hope this was helpful!
Is number of days absent from school and the mark in the examination a positive and negative or no correlation?
No correlation. The mark you get in your exam, relates to the number of correct answer you have given. It has nothing to do with your class attendance.
What is a correlation statement?
a correlation statement is a sentence that says whether the points on a scatterplot have a positive, negative or no correlation.ex. This graph shows a negative correlation, as the number of cows increases (x axis data) the profitability decreases (y axis data).
Is this positive or negative correlation the number of computers per school and the number of students per computer?
positive
Is the time elapsed and the number of words typed negative or positive correlation?
It would be a positive correlation. As the time increases, the number of words typed would also increase.
Is the age of pets in a home and the number of pets in that home a positive negative or no correlation explain?
Possibly
