You measured the strength of a spring at a breaking point based on the pressure at which it was produced. Your assumption is that breaking strength is correlated to pressure.

Question: Are the two variables linked/dependent?

Left hand table: Depending on the comparison to be carrid out This test does not appear in left hand table.

Right hand table: Depending on the types of variables Y is the result of the resistance measurement (quantitative) based on (X) a measure of production pressure (quantitative). The test you should choose is simple regression.

To analyze the data, enter the values by organizing them into two columns.

Based on the regression test, the correlation between pressure and resistance is not significant. We can, therefore, not conclude that production pressure has an impact on a product's resistance.
