In which phase s of a design process might statistics be most useful? 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 a statistical analysis to estimate measures of central tendency and variation of a product wooden cubes. The statistics can help determine the product's consistency which may help for shaping the product and finding outliers that need to be fixed. I think that there would be around 19 or 20 acceptable cubes because there were at least 4 cubes too big and 4 cubes too small. You will research and document your findings using careful measurements, sketches, and notes which will complete the reverse engineering of your product. Some would say the designer creates specifications, which in turn dictate the quality of a product. You will also represent the data using a histogram.
