Normal Distribution

How is the graph distributed?

• Normally

• Skewed to the Left

• Skewed to the Right

• Uniform

According to the empirical rule, what percentage of data falls within 1 standard deviation? 

• 25%
• 68%
• 95%
• 99.7%

According to the empirical rule, how much of the data falls within 3 standard deviations? 

• 25%
• 68%
• 95%
• 99.7%

Describe the graph

• skewed right

• skewed left

The data in the picture:

• skewed left

• skewed right

• Normal/symmetrical

Describe the graph

• skewed right

• skewed left

How would an outlier added to the far left of the graph affect the mean and medians' relationship?

• The mean would be farther less than the median

• The mean and median would be closer to each other

If there was an outlier added to the far right of this graph, how would it affect the mean and medians' relationship?

• mean > median

• mean < median

• Mean = Median
