Question

3 multiple choice 1 point a student wants to improve their sleep consistency by tracking bedtime. which measurement approach best meets the objective and observable criteria? \ill record how well - rested i feel each morning on a 1 - 10 scale and note whether i had a good night or bad night of sleep.\ \ill track bedtime when i feel tired enough to sleep and record early bedtime for before 11 pm and late bedtime after 11 pm.\ \ill use my phones automatic bedtime tracking and record the exact time i put my phone in airplane mode next to my bed each night.\ \ill measure sleep quality by how many hours i think i slept and whether i remember waking up during the night.\

Explanation:

The objective is to track bedtime for sleep - consistency improvement. The first option measures how well - rested one feels, not bedtime. The second option has a subjective definition of 'feeling tired enough'. The fourth option measures sleep quality rather than bedtime. The third option uses the phone's automatic tracking to record an objective and observable bedtime (the time the phone is put in airplane mode next to the bed).

Answer:

"I'll use my phone's automatic bedtime tracking and record the exact time I put my phone in airplane mode next to my bed each night."
