graph would show a

positive correlation
positive answer
negative correlation
negative answer

Respuesta :

From the options listed The graph would show a negative correlation  ( C )

Correlation is used to express the relationship between two or more variables.  correlation can be measured into four ( 4 ) in statistics :

  • Pearson correlation
  • Kendall rank correlation
  • Spearman correlation
  • Point-Biserial correlation

But Generally correlation is categorized as either a positive or a negative correlation.

In a negative correlation the variables are inversely proportional to each other while in a positive correlation the variables are directly proportional to each other.

Note : an inverse proportion simply means that an increase in value of one variable = decrease in value of the other and vice versa

hence the graph would show a negative correlation given that the the values of the motorcycle decreases with increase in time.
