Nettet5. apr. 2024 · We can see that SED and MVPA are strongly correlated with states 0–1 (rho = 0.67), and 4–5 (rho = 0.82), respectively. SED is negatively correlated with states 4–5 (rho = -0.28) and MVPA negatively correlated with states 0–1 (rho = -0.39). LPA does not show strong correlation with any state grouping.
