Question

if the points on a scatterplot trend upward from left to right, what kind of correlation is shown?

• causal relationship
• no correlation
• negative correlation
• positive correlation

Explanation:

A positive correlation is defined as a relationship where as one variable increases, the other variable also increases, which appears as an upward trend from left to right on a scatterplot. A causal relationship implies one variable causes the other, which is not indicated by just a trend. No correlation means no visible trend, and negative correlation shows a downward left-to-right trend.

Answer:

Positive correlation
