Mini Research In Math Grade 10 Pdf < BEST × 2024 >

y = 1058x – 1174 Step 3: Check Correlation Looking at the data, most points are close to the line, but there are outliers (e.g., iPhone 15 Pro Max has a smaller battery than expected for its size). This suggests a moderate to strong positive correlation (estimated correlation coefficient r ≈ 0.85). 6. Conclusion (Answering the Question) Does a linear relationship exist? Yes. Our data supports the hypothesis that screen size and battery capacity have a positive linear relationship.

This means: for every extra inch of screen size, battery capacity increases by about 1058 mAh. mini research in math grade 10 pdf

April 16, 2026 1. Introduction (The Question) Smartphones are a big part of our daily lives. When people buy a new phone, they often want a large screen but also long battery life. This leads to an interesting question: y = 1058x – 1174 Step 3: Check

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. This means: for every extra inch of screen
