The spread of the data:
Our data ranged from 34 to 214, and the range is 180.
The interquartile range shows us the middle fifty percent of the data. It is 62.
The variance is the average of the squared deviation. They must be squared because some are negative. The variance is 2200.0790.
The standard deviation is the square root of the variance, which is 46.905 Noted Patterns in the data?

The data drawn from the Women's Volleyball games from the olympics shows that teams scored closer to 90-116 than any other grouping of scores. This causes our histogram to show a bell-shaped curve with more scores after than before, but still ranging around the mean value.
The reason for the the scores mainly in the 90-116 range is because of the vigorous competition that these teams went through while playing eachother. The ladies on the Women's Volleyball team are the best in the world. What is an attack? When the offensive team
hits a very intense, fast throw
using the palm of their hand and

attack on the other team, and hopefully
an instant point.
