G10 Remedial Task 001

What does positive correlation means?

• As one variable increases, the other decreases.

• As one variable decreases, the other increases.

• As one variable increases, the other also increases.

• No changes on the other variable whether they increases or decreases.

What type of correlation has defined when one variable increases, the other decreases?

• Positive

• Negative

• Neutral

• No Correlation

What type of correlation does the graph show?

• Positive

• Negative

• No Correlation

• Neutral

What is the use of the line of best fit in a scatter graph?

• to count the number of subjects

• to know how the percentage of the subjects

• To predict the value

• to know the type of correlation

What do you mean by an "outlier"?

• Data point that exactly lies on the line of best fit

• Data point that scatter around the line of best fit.

• Data point that scatter the farthest from the line of best fit.

• Data at the origin

How do you describe the line of best fit for positive correlation?

• Horizontal line

• Rising to the right

• Rising to the left

• vertical line

What do you call to the process of extending the line of best fit outside the range of the collected data?

• Excursion

• Extension

• Extrapolation

• Intrapolation

Why is the predicted value in the extrapolation unreliable?

• It is out of the range of collected data

• It does not happened

• There is no correlation outside the range of collected data

• It's unpredictable

What type of correlation is shown in the graph?

• Positive

• Negative

• Neutral

• No correlation

What type of correlation is shown in the graph?

• Positive

• Negative

• Neutral

• No correlation
