we performed aχ²-Test for association (Fig.5b) (Agresti,2013,2018; McHugh,2013). Two assumptions underlie aχ²-Test: the independence of data and expected frequencies in the contingency table exceeding five (Howell,2006; Field et al.,2012). In our study—although students...
the number of grid points was recorded where eitherMAT1-1orMAT1-2or both mating types were found. A contingency table test for independence of the spatial distribution of the mating types
Logistic regression (LR) is one of the most used estimation techniques for nominal data collected in contingency tables, and the question arises how the recently proposed concept of nominal correlation and regression (NCR) relates to it. (1) LR targets the cells in the contingency table while ...
Within this article, when the buyer or customer is referred to in a B2B context then this relates to the buying firm since the B2B buying process involves more than one person. A group of buyer personnel are involved in the buying process (Grewal et al., 2015) involving a wide range of...
histogram and a probabilistic density analysis of body size to investigate the sizes of snakes involved in snakebite incidents in this region. Additionally, to investigate the association between snake sex and the time of day of the envenomation, we conducted a contingency table and chi-square ...
chisquare() assumes a goodness-of-fit test while chi1_contingency() assumes a contingency table. Experimental design must address confounding factors that might also account for the variance. You want to minimize confounding factors but there is such thing as controlling for too many confounding ...

Finally, the mathematical object approach closely relates to Sfard’s structure approach, as both refer to a holistic view of functions. The mathematical object approach stresses understanding various aspects of functions and connecting different representations of them (e.g., formulas and graphs). ...
Rather, ACT intends to promote psychological health by changing how one relates to those events and reduce their behavioral impact, thus laying the foundation for actions that move individuals towards valued and meaningful living [38]. ACT’s perspective on psychological health is closely tied to ...
