Applied Statistics
I created a histogram based upon the given information and also found the Standard Deviation of the proceeding:
Part of the manufacturing quality control testing for a toy is to measure the depth of a connector piece that must fit into another part. The designed depth is 4.1 cm. Every tenth part produced on the production line is measured. The following data was collected during a two minute production period.
4.1, 4.1, 4.0, 4.1, 3.9, 4.4, 3.9, 4.3, 4.0, 4.2, 4.0, 3.8

Standard Deviation
Proceeding calculating the measures of central tendencies I found the measures of variation in depth using by subtracting Average (4.0666667 cm) from the depth of each cube. Then once I had the value of variation I would square it, then once I had the squares for all the values of variations I added the values together.
Once I had added the values together I then subtracted that sum by 12 (the quantity of cubes) to find the Standard deviation of the Data which is approximately 0.0273
