MATH 110 Lecture Notes - Lecture 26: Skewness, Sampling Distribution
Document Summary
Math 110 lecture 26 different types of graphs. Is one in which every possible different sample has an equal chance of being chosen from a population. This can be shown with a bell curve, where, as the peak becomes higher, the sample size increases and the shape becomes narrower. Is a set of numbers describing some aspect of a population. Is a graphical interpretation of a distribution, such as illustrating where student scores lie on a horizontal scale. Note: the dots on the graph would represent each students" scores. If we were to draw a line number it, then mark a dot over each number to represent every score, we would see that 19 was the most common score earned. Here, we divide the overall range of values into bins. Bins should be of equal size, except that a bin at one or the other end have one extra number.
