Scatter Plot Introduction

When points in the scatter plot appear to form two or more distinct clouds of points, it's called...

• clusters

• bunches

• groups

• cliques

What type of association or correlation does the scatter plot represent?

• positive

• negative

• no

What kind of pattern or trend do you see?

• a slight upward trend

• a slight downward trend

• no pattern visible

When the scatter plot shows an increase in the outputs as the inputs are increasing

• positive correlation

• negative correlation

• no correlation

What pattern do you see in the data?

• positive correlation

• negative correlation

• no correlation

What is a scatter plot?

• A graph that shows the relationship of two data sets.

• A graph drawn using rectangular bars to show how large each value is.

• A graph that shows information that is connected in some way.

• A graph that shows data changing over time.

What type of correlation does this graph have?

• positive

• negative

• none

• all of the above

Which relationship could be represented by this scatter plot?

• As the number of muffins in a box increases, the price increases.

• As the speed of a car increases, the distance the car travels increases.

• As the population of a city increases, the number of schools in the

  city increases.

• As the number of daylight hours increases, the number of night hours decreases.

What type of correlation does this graph have?

• Negative

• no association

• positive

If a scatterplot has no association then...

• ...it has no ordered pairs

• ...it has ordered pairs that have a negative pattern

• ...its ordered pairs have no predictable pattern

• ...if it makes a lion on a graph (roar!)
