Question

claim 3. iphone batteries last longer than android batteries. (5 pts)
hypothesis: if __________________, then __________________
independent variable: \t\t\tcontrol(s):
dependent variable: \t\t\t
experimental group \t\t\t

Explanation:

Hypothesis:

If a device is an iPhone (using an iPhone battery) and another device is an Android (using an Android battery), then the iPhone battery will last longer than the Android battery when both devices are used under the same conditions.

Independent Variable:

The type of phone battery (iPhone battery vs. Android battery)

Dependent Variable:

The duration the battery lasts (battery life)

Control(s):

• The type of tasks performed on the devices (e.g., same apps used, same screen brightness, same network conditions)
• The initial battery charge level (e.g., both start at 100% charge)
• The model of the devices (e.g., using a specific iPhone model and a specific Android model with similar hardware specifications other than the battery)

Experimental Group:

• Group 1: Devices with iPhone batteries (e.g., iPhones)
• Group 2: Devices with Android batteries (e.g., Android phones)

These groups will be tested under the controlled conditions to compare the battery life.
