The correlation coefficient is a value between -1 and 1

• True

• False

  The correlation coefficient can't take any negative values

• False

What is the type of this plot?

• Stacked Bar plot

• Unstacked Bar plot

• Histogram

• Scatter plot

One of the best time to use line plot is

• When y axis contains date values

• When there is no date values

• When X axis contains date values

• When we want to visualize two categorical variables

Which statement can describe the plot (you can choose more than one answer)

• There is a negative correlation betwen weight and cost

• There is a positive correlation between weight and cost

• As long as the weight increases the cost decreases

• As long as the weight increases, the cost also increases

This type of plot is

• Histogram

• Scatter plot

• Line plot

• Heat map

This plot is

• Bar plot

• Unstacked bar plot
