Mathematics (Linear Relations, Data Analysis, Correlation) This means: for every extra inch of screen

Using point A: 2000 = 1058(3.0) + b 2000 = 3174 + b b = 2000 – 3174 = -1174 If a phone’s screen is 1 inch larger,

In this mini research, we will collect data from real phones to see if the relationship is linear (a straight line), positive (bigger screen = bigger battery), or if there is no clear relationship. Based on common sense, a larger screen requires more energy to light up. Therefore, phone manufacturers usually put a larger battery inside a phone with a larger screen.

If a phone’s screen is 1 inch larger, you can expect the battery to be roughly 1000 mAh bigger. However, the relationship is not perfect—Apple’s iPhones tend to have slightly smaller batteries than Android phones of the same size, because their software is more power-efficient.
