Question

question 2 1 pts a total of 480 students participate in an experiment in which a researcher seeks to determine whether performance on a mathematics task depends on two conditions: (1) the posture students are instructed to adopt while solving the task (either sitting up straight or slouching) and (2) the time of day in which the task is completed (either in the morning, afternoon, or evening). from this information, we know the experiment has __________ treatments. please enter your answer, in the form of a number, in the box below.

Explanation:

Step1: Identify number of levels for each factor

There are 2 postures (sitting up straight, slouching) and 3 times of day (morning, afternoon, evening).

Step2: Calculate number of treatments

The number of treatments is the product of the number of levels of each factor. So, $2\times3 = 6$.

Answer:

6
