<h2>
If two sets of data are correlated, this means that: one set causes the other to happen.
</h2>
Explanation:
Correlation indicates a relationship between two or more variables, but this relationship does not suggest cause and effect. When two sets of data are correlated, it means that as one variable changes, the other variable also changes.
The correlation can be measured by calculating a statistic called as correlation coefficient. The number from -1 to +1 indicates the strength and direction of the relationship between variables. The correlation coefficient is denoted by the letter r.

Answer:
<em>The wave will be travelling in the y-axis</em>
Explanation:
An e-m wave has a spatially varying electric field that is always associated with a magnetic field that changes over time and vice versa. The electric field and the magnetic field oscillates perpendicularly to each other, and together form a wave that travels in a perpendicular direction to the magnetic and the electric field in space. The movement of the e-m wave through space is usually away from the source where it is generated. So, if the electric field travels in the z-axis, and the magnetic field travels through along the x-axis, then the e-m wave generated will travel in the y-axis direction.
