    1. Giving more money to the police, or expanding the number of police, should be opposed, she says, because such actions allow police to harass and incarcerate marginalized people with greater efficiency.

      This is a correlative argument by saying the increase of money in the broken system will cause it to become even more corrupt. A little bit further down, it talks about body cams and how with access to do that officers are able to change the footage to their liking.

    1. Nick Sawyer, MD, MBA, FACEP [@NickSawyerMD]. (2022, January 3). The anti-vaccine community created a manipulated version of VARES that misrepresents the VAERS data. #disinformationdoctors use this data to falsely claim that vaccines CAUSE bad outcomes, when the relationship is only CORRELATED.

    1. The magnitude of the Pearson correlation coefficient determines the strength of the correlation. Although there are no hard-and-fast rules for assigning strength of association to particular values, some general guidelines are provided by Cohen (1988):

      Magnitude of pearson correlation coeficient.

    1. move away from identifying correlative relationships between characteristics of the microbiome and system-level processes, and towards identifying more causative and mechanistic relationships

    1. relationships between characteristics of microbiomes and the system-level processes that they influence are often evaluated in the absence of a robust conceptual framework and reported without elucidating the underlying causal mechanisms. The reliance on correlative approaches limits the potential to expand the inference of a single relationship to additional systems and advance the field

    1. You may believe that there is a relationship between 10,000 m running performance and VO2max (i.e., the larger an athlete's VO2max, the better their running performance), but you would like to know if this relationship is affected by wind speed and humidity (e.g., if the relationship changes when taking wind speed and humidity into account since you suspect that athletes' performance decreases in more windy and humid conditions).

      An example of partial correlation.

    1. Assess-ing causality is one of the most needed futuredevelopments in SciSci: Many descriptive studiesreveal strong associations between structure andoutcomes, but the extent to which a specific struc-ture“causes”an outcome remains unexplored.

    1. Figure 1.8

      Several sets of (x, y) points, with the correlation coefficient of x and y for each set. Note that the correlation reflects the non-linearity and direction of a linear relationship (top row), but not the slope of that relationship (middle), nor many aspects of nonlinear relationships (bottom). N.B.: the figure in the center has a slope of 0 but in that case the correlation coefficient is undefined because the variance of Y is zero.
