Activity 3.5 Applied Statistics
Introduction
Today’s consumers are constantly trying to judge the quality of products. But what is quality? How and by whom is quality determined? Some would say the designer creates specifications, which in turn dictate the quality of a product. That quality is also based on the acceptable value of a part within a whole product. Statistics are commonly used in manufacturing processes to control and maintain quality. This activity will allow you to apply statistics in order to analyze and determine the quality of a set of wooded cubes.
In this activity you will collect data and then perform statistical analyses to determine measures of central tendency and variation of the data. You will also represent the data using a histogram.

Conclusion
1. How can statistics of a product’s dimensions be used to assess the quality of the product? The statistics can help determine the product's consistency which may help for shaping the product and finding outliers that need to be fixed.
2. In which phase(s) of a design process might statistics be most useful? Why? Statistics may prove most useful when doing technical drawings so you can find what you might want/need to change before building the prototype instead of having to go back a step.
