    The document provides data on mathematics and statistics scores for 10 students. It includes the raw scores for each student, as well as totals. It then uses this data to calculate the correlation coefficient (r) between the two sets of scores. The r value calculated is 0.92, indicating a very high positive relationship between the students' mathematics and statistics scores.

    SOLUTION:

    𝑁 ∑ 𝑥𝑦 − ∑ 𝑥 ∑ 𝑦
    𝑟=
    √[𝑁 ∑ 𝑥 2 − (∑ 𝑥)2 ][𝑁 ∑ 𝑦2 − (∑ 𝑦)2 ]

    10(6039) − (259)(224)
    𝑟=
    √[10(7159) − (259)2 ][10(5164) − (224)2 ]

    2374
    𝑟=
    √6601176

    𝒓 = 𝟎. 𝟗𝟐 “Very High Positive”
