Quizplus · Accepted Answer

The correct choice is A because it accurately describes the subjects of the study (all days in January 2014), identifies each day as a separate case, lists the variables collected (high and low temperatures, precipitation, humidity, and wind speed), specifies the time frame (January 2014), the location (Ontario), the purpose (research for a science class), and acknowledges that the method of data collection is not specified.
