For each measure below, indicate which kinds of reliability would need to be evaluated. Then draw a scatterplot indicating that the measure has good reliability and another one indicating the measure has poor reliability. C. Psychologists measure how long it takes a mouse to learn an eyeblink response. For 60 trials, they present a mouse with a distinctive blue light followed immediately by a puff of air. The 5th, 10th, 15th trials are test trials, in which they present the blue light alone(without the air puff). The mouse is said to have learned the eyeblink response if observers record that it blinked its eyes in response to test trials. The earlier in the 60 trials the mouse shows the eyeblink response, the faster it has learned the response.
