If the values of two variables move in the same direction, then the correlation is said to be __________a.Non-linearb.Linearc.Positived.NegativeClear my choice

Break Down the Problem

1. Identify what correlation means in statistics.
2. Determine the relationship between variables based on their movements.

Relevant Concepts

1. Correlation: It is a statistical measure that expresses the extent to which two variables are linearly related.
2. Types of Correlation:
   • Positive Correlation: When the values of two variables move in the same direction.
   • Negative Correlation: When the values of two variables move in opposite directions.
   • Linear Correlation: Indicates a straight-line relationship between the variables.
   • Non-linear Correlation: Indicates a relationship that isn’t adequately described by a straight line.

Analysis and Detail

1. If two variables move together, they exhibit a positive relationship.
2. Therefore, if one variable increases, the other also increases, which is characteristic of positive correlation.

Verify and Summarize

Based on the definitions and concepts above, the correct answer must relate to the behavior of the variables.

Final Answer

The correlation is said to be c. Positive.
