Worked Solution & Example Answer:The scatter graph shows information about the marks of students got in a Science test and in a Maths test - Edexcel - GCSE Maths - Question 4 - 2019 - Paper 3
Step 1
Using the scatter graph
Answer
To estimate Jamie's Maths mark, we begin by locating the Science test mark of 34 on the horizontal axis of the scatter graph. From this point, we can draw a vertical line upwards to intersect with the scatter points. This intersection will lead us to the corresponding Maths mark on the vertical axis.
Step 2
Determine the Maths mark
Answer
Following the vertical line upwards from the point where Science mark is 34, we find that the intersection lies approximately between the Maths marks of 35 and 42. This suggests that Jamie's Maths mark closely aligns with this range, giving an estimated result around 38.
