Math Problem Statement
Solution
The image shows a scatter plot that displays the relationship between "Usia Siswa (tahun)" or student age (in years) on the x-axis and "Ukuran Sepatu" or shoe size on the y-axis for several high school students ("SMA Eflangga"). The question asks which statement best describes the correlation based on the scatter plot.
The choices are: a) The diagram shows a negative correlation. b) The diagram shows no correlation. c) The diagram shows a positive correlation. d) The diagram shows a strong correlation.
Upon inspecting the scatter plot, the points seem to be scattered randomly, with no clear upward or downward trend. This implies that there is no apparent relationship between age and shoe size for this data set.
Thus, the correct answer is:
b) The diagram shows no correlation.

- What factors affect the strength of a correlation?
- In what situations might you expect a correlation between age and shoe size?
- How can you interpret weak correlations in data?
Tip: In scatter plots, a clear trendline (either upward or downward) suggests a correlation, while a random scattering indicates no correlation.
