The median of a data set is the data point in the middle of a set. The median is a good measure for finding the center values of a data set to find a decent "average" or a control group. It is also a useful point of reference for finding outliers. The mode is the data point that occurs most frequently in a set. This is a good measure for seeing the frequency of certain responses in things like experiments or surveys. The mean is the average of a data set. This is a good measure for finding a representative number for the general points of a data set, and also a good method of finding outliers. If the mean doesn't seem right, your set likely has an outlier.
I don’t have any questions initially about logic- it's all, for lack of a better word, logical. p, q, and r are all visually distinct letters that can be easily told apart at a glance, and are all next to each other sequentially in the alphabet, which makes them easy picks. Sentences that are not statements are questions (“Is Jurassic Park a good movie?”,) commands (“Go watch Jurassic Park!” , ) and opinions (“Jurassic Park is a cinematic masterpiece.”) A statement that is both true and false is a paradox (which is sort of inherently a paradox in and of itself, given that a paradox is both true and false,) but because a paradox inherently somehow contradicts itself in one way or another it either cannot be true or cannot be false. Statement: “Most theropod dinosaurs had feathers.” Symbolic: p= “Most theropod dinosaurs had feathers.” Negation: “No theropod dinosaurs had feathers,” or alternatively “All theropod dinosaurs had feathers...
