Question

students are comparing how long they charge their phones for in hours,
with the percentage of charge shown on their phones.
a) draw a scatter graph to represent the results for these six students.
dani (5, 80) ron (3, 70)
kim (0, 10) eddy (7, 100)
nijah (10, 4) brett (5, 60)
b) whose phone do you think is broken?
explain your reasoning.

Explanation:

A scatter graph plots points based on two variables (charging hours and charge percentage). Typically, as charging hours increase, charge percentage should increase. Nijah has the most charging hours (10) but the lowest charge percentage (4), which is an out - of - pattern result compared to others.

Answer:

Nijah. Because usually, more charging hours would lead to a higher charge percentage, but Nijah has 10 hours of charging (the most among them) and only 4% charge, which is inconsistent with the general trend (if we assume a positive relationship between charging time and charge percentage).
