The correlation coefficient between two quantitative variables is approximately 0.6. What does the value of this correlation coe
murzikaleks [220]

Answer:

The model does not fits the data well.      

Step-by-step explanation:

Correlation:

  • Correlation is a technique that help us to find or define a relationship between two variables.
  • It is a measure of linear relationship between two quantities.
  • A positive correlation means that an increase in one quantity leads to an increase in another quantity
  • A negative correlation means with increase in one quantity the other quantity decreases.

R-square, R^2

  • The quantity R-squared is an indicator of the predictive power of a model.
  • It explains the variation in the dependent variable due to independent variable.
  • It shows how well the model fits the data.
  • R-squared is also known as the  coefficient of determination.

R^2 = \text{(Correlation coefficient)}^2= (0.6)^2 = 0.36 = 36\%

Therefore, only 36% of the variations in the dependent variable is explained by the independent variable in the model which means more than 50% of variation cannot still be explained in the dependent variable.

Hence, the model does not fits the data well.

nignag [31]

Answer:

1. 247 mg ÷ 10 = 24.7 cg

2. 247 mg ÷ 100 = 2.47 dg

247 mg ÷ 1000 = 0.247 g

Step-by-step explanation:

1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.

2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.

3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.
