Sierra College students enrolled in an online Elementary Statistics course were asked to participate in an anonymous online survey. The survey asked the students "Which type of device will you primarily use to access your online course in Canvas?". Of the 153 students who answered this question, 31 responded "a desktop computer", 113 responded "a laptop computer" 6 responded "a smartphone", and 3 responded a tablet". The Sierra College Mathematics Department believes that less than 5% of students enrolled in an online Elementary Statistics course primarily uses a smartphone to access their online course in Canvas.
