Unit Understandings

Unit 3 Measurement and Statistics U1 – Error is unavoidable when measuring physical properties, and a measurement is characterized by the precision and accuracy of the measurement. U2 – Units and quantitative reasoning can guide mathematical manipulation and the solution of problems involving quantities. U3 – Dimensions are included on technical drawings according to accepted practice and an established set of standards so as to convey size and location information about detailed parts and their features. U4 – Statistical analysis of uni-variate data facilitates understanding, and interpretation of numerical data and can be used to inform, justify, and validate a design or process. U5 – Spreadsheet programs can be used to store, manipulate, represent, and analyze data efficiently.

Unit Knowledge

Unit 3 Measurement and Statistics K1 – Identify general rules for dimensioning on technical drawings used in standard engineering practice. U5 K2 – Distinguish between sample statistics and population statistics and know appropriate applications of each. K3 – Distinguish between precision and accuracy of measurement.

unit skills

Unit 3 Measurement and Statistics S1 – Measure linear distances (including length, inside diameter, and hole depth) with accuracy using a scale, ruler, or dial caliper and report the measurement using an appropriate level of precision. U1 S2 – Use units to guide the solution to multi-step problems through dimensional analysis and choose and interpret units consistently in formulas. U4 S3 – Convert quantities between units in the SI and the U.S. Customary measurement systems. U4 S4 – Convert between different units within the same measurement system including the SI and U.S. Customary measurement systems. U4 S5 – Dimension orthographic projections of simple objects or parts according to a set of dimensioning standards and accepted practices. U5 S6 – Identify and correct errors and omissions in the dimensions applied in a technical drawing based on accepted practice and a set of dimensioning rules. U5 S7 – Calculate statistics related to central tendency including mean, median, and mode. U6 S8 – Calculate statistics related to variation of data including (sample and population) standard deviation and range. U6 S9 – Represent data with plots on the real number line (e.g., dot plots, histograms, and box plots). U6 S10 – Use statistics to quantify information, support design decisions, and justify problem solutions. U6 S11 – Use a spreadsheet program to store and manipulate raw data. U10 S12 – Use a spreadsheet program to perform calculations using formulas. S13 – Use a spreadsheet program to create and display a histogram to represent a set of data. S14 - Use function tools within a spreadsheet program to calculate statistics for a set of data including mean, median, mode, range, and standard deviation. S15 - Use the Empirical Rule to interpret data and identify ranges of data that include 68 percent of the data, 95 percent of the data, and 99.7 percent of the data given the appropriate descriptive statistics. S16 - Choose a level of precision and accuracy appropriate to limitations on measurement when reporting quantities. S17 - Evaluate and compare the accuracy and precision of different measuring devices. S18 - Calculate Cost of Goods (COG) for product design and manufacture. S19 - Accurately measure properties associated with a given quality control standard. S20 - Analyze and interpret results of quality control data. S21 - Demonstrate safe use of hand tools and shop tools.
