Answer:
It states that time spent on social networking sites & twitter have a strong positive correlation.
Step-by-step explanation:
Correlation is the statistical measure of co-movement relationship between two variables. Correlation Coefficient 'r' lies between -1 & +1
Correlation can be following on basis of variables relationship direction
- Positive Correlation : It means two variables move in the same direction - one variable increase, other variable increase & one variable decrease, other variable decrease. 'r' is positive.
- Negative Correlation : It means two variables move in opposite direction - one variable increase, other variable decrease & one variable decrease, other variable increase. 'r' is negative.
Correlation can be following on the basis of variables :
- Strong Correlation : It means the variables fluctuations are more inter-related. r > 0.5
- Weak Correlation : It means the variables fluctuations are less inter-related. r < 0.5
Correlation between times spent on social networking sites & twitter is 0.8 This r = 0.8 means that the two activities have strong positive correlation. It implies that increase in one lead to increase in other activity & vice versa, by a high magnitude.
The correlation coefficient of 0.8 shows that the relationship between spending time on social networking sites and Tw-itter has a strong positive correlation.
What does the correlation show?
The correlation coefficient shows the relationship between two measures which in this case are spending time on social networking sites and spending time on Tw-itter.
The closer a coefficient is to 1, the stronger the correlation. If this coefficient is positive then the relationship is positive.
Due to the proximity of 0.8 to 1, we can say that the relationship here is a strong positive correlation.
