;Question-1 The following table provides measurements from a scientific experiment. sample number density (X) velocity (Y) 1 2.8 1.5 2 8.5 7.7 3 1 3.6
;Question-1
The following table provides measurements from a scientific experiment.
sample | number | density | (X) | velocity | (Y) |
1 | 2.8 | 1.5 | |||
2 | 8.5 | 7.7 | |||
3 | 1 | 3.6 | |||
9.5 | 5.1 | ||||
5 | 7.5 | 8.7 |
To measure the correlation between density and velocity, we should use the
- Spearman correlationcoefficient
- Pearson correlationcoefficient
