Intro to Discrete Maths Exam Questions and Answers All Correct 1. p→q 2. p ↔q 3. ¬(p↔q) 4. (p→r) ^ (q→r) 5. (p→q) V (p→r) 6. (p→r) V (q→r) - Answer-1. ¬q→¬p 2. (p→q) ^ (q → p) 3. p ↔ ¬q 4. (p v q) → r 5. p → (q V r) 6. (p ^ q) → r the conjunction operator takes precedence over the disjunction operator, so that p∨q∧r means p∨(q∧r) rather than (p∨q)∧r and p∧q∨r means (p∧q)∨r rather than p∧(q∨r). - Answer-Because this rule ...

Discrete Data Values are whole numbers (integers) -Usually counted, not measured Continuous Data Can potentially take on any value, depending only on the ability to measure accurately -Often measured, fractional values are possible Discrete Random Variables have outcomes that typically take on whole numbers as a result of conducting an experiment Continuous Random Variables have outcomes that take on any numerical value as a result of conducting an experiment or -out...

continuous random variable - random data that can take on any values within some interval discrete random variable - a countable set of values density curve - A mathematical model for a probability distribution of a continuous random variable uniform density curve - describes a variable that takes values that are uniformly spread between a range of values normal distribution - Common type of probability distributions for continuous random variables

Kinesiology correct answers the study of the art and science of human movement Measurement correct answers the process of comparing a value to a standard (Distance, force, time, frequency) Data correct answers the result of movement Statistics correct answers a mathematical technique by which data are organized, treated, and presented for interpretation and evaluation Reliability correct answers reproducibility, consistency Validity correct answers the soundness or the appropriate...
