1.
We have X and Y variables in the dataset which have a corrrelation of 0.75
X | Y |
123 | 112 |
178 | 214 |
116 | 156 |
119 | 123 |
125 | 114 |
154 | 222 |
140 | 168 |
104 | 165 |
164 | 234 |
152 | 143 |
150 | 170 |
158 | 201 |
168 | 267 |
This correlation is positive, which means that if X increases, Y increases. If X decreases, Y will decrease. Please note that correlation doesn't imply causality

We have X and Y variables in the dataset which have a corrrelation of -0.89
X | Y |
156 | 23 |
231 | 12 |
47 | 156 |
24 | 167 |
134 | 101 |
8 | 305 |

5 | 289 |
2 | 343 |
34 | 201 |
43 | 187 |
45 | 250 |
It means that the correlation is negative, i.e. if X increases, Y decreases. Also, a correlation of -.89 means it is a linear correlation of good strength. Correlation doesn't imply causality
