How to describe a sample Inferential Statistics Bi Modal Central TendencyMultimodal having more than 2 modes Unimodal When distribution only has one mode -the frequencies progressively decline as they move away from the mode. Symmetrical distributions are usually uni modal. bimodal means you have not defined your population if you find a bimodal Mode most frequently occurring measure (value or category) in (distribution) data Mean called location parameter most frequen...

addition rule - a mathematical rule used to calculate the probability of the union of events alpha - The probability of rejecting the null hypothesis when, in reality, it is true. Alternative hypothesis - Designated H1, this hypothesis represents the opposite of the null hypothesis and holds true if the null hypothesis is found to be false. The alternative hypothesis always states the population parameter is <, not equal (=/), or > a specific value. bar chart - A chart that displays q...

Suppose a political party wants to estimate how favorable a certain candidate is to state voters. To do so, a sample of 400 registered voters were selected. Suppose 160 found the candidate "favorable". An estimate of the proportion of the population of registered voters is 160/400=40%. This is an example of what? Example of finite sample Suppose a new tire is being developed and the manufacturer wants to know the useful life of the new type of tire. A sample of 120 tires were tested an...
