Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition P. 1 Data Analysis and Presentation for Written and Oral Reports Week 6 Day 1

Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition P. 2 This Week Wednesday – Documenting the Robot Electrical Systems – Work day Friday - –Robot Performance Test Four – Set robot for side, Read the start signal from the LED, go to patient’s IR task beacon, activate patient task switch, read task, go up the ramp or stairs, go to mailbox and stop in front of mailbox, print “Mailbox” on display at mailbox Testing Time - Need to keep track of testing time on the robot course - 10 minute increments

Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition P. 3 Data Analysis and Presentation Possible Graphs –x-y plot of a single data set, multiple data sets –Bar charts - horizontal, vertical - comparison

Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition P. 4 Data Analysis and Presentation –Pie charts - Good for parts of a whole –Budgets –Time spent –Project schedule done in graphical form

Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition P. 5 Data Analysis and Presentation Data generally is available in tables –Tables are necessary for many types of data BUT –They can be Hard to Read and Understand –When used, they should include Appropriate Title, Column Headings, Units Use spreadsheet or word processor Read from right or bottom of page Graphs provide easier understanding of data Your team may want to use both

Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition P. 6 Data Analysis and Presentation Spreadsheet graphs are one place to start –Don’t trust them to give good graphs Format for Graphs –Appropriate Grid –Even numbers on Grid, Highest # greater than max data point –Title and axis labels (labels need units) –Multiple plots need different symbols - legend –Use smooth curve when data points fit equation –Use points connected with straight lines when there is no equation that relates the independent and dependent variables
