**Correlation and Causation Flashcards Quizlet**

Both variables need to be quantitative to calculate correlation. The correlation r does not change if we change the units of measurements of x, y, or both. A positive r corresponds to a positive relationship between the variables.... The critical shear strength of soil is proportional to the effective normal stress; thus, a change in effective stress brings about a change in strength. Therefore, if the pore pressure in a soil slope increases, effective stresses will be reduced by Ds ' and the critical strength of the soil will be reduced by Dt - sometimes leading to failure.

Compressive strength is an effective way of measuring how much load a surface or material can bear. The test for this sort of strength is performed by exerting force downward on top of the object, paired with an equal and opposite force exerted upward on the bottom.... Flexural strength is the measure of the tensile strength of concrete. It is measured in terms of stress, whose symbol is σ . Flexural strength is a measure of an unreinforced concrete beam or slab to resist failure in bending.

## How To Calculate The Change In Causation Strenght

"Correlation does not imply causation" is a phrase used in statistics to emphasize that a correlation between two variables does not imply that one causes the other. [1] [2] Many statistical tests calculate correlation between variables .

- Increase in panel yield strength cause the increase of panel dent resistance. Consider that if automotive exterior panel thickness decreases to reduce vehicle weight, then panel sheet material should be change to prevented distorted panel dent resistance property. Table 2. Comparison between simulation and Yutori equation in 0.1 mm dent depth with Yutori modified parameter Yield strength (Mpa
