... The primary use of descriptive statistics is to describe information or data through the use of numbers (create number pictures of the information). The characteristics of groups of numbers representing information or data are called descriptive statistics. Descriptive statistics are used to describ ...

... d. Tony, Sasha, and Derman separately traveled this bus route and calculated their z-scores: z = 0.3 for Tony, z = –1.5 for Sasha, and z = 2.1 for Derman. Find their travel times. e. Using an appropriate calculator function, approximate the probability that the travel time on this bus route, rounded ...

Consequence, inconsistency, i.e. larger sample sizes do not lead to lower standard errors for the parameters, and the parameter estimates (slope etc.) are biased. • The error is not distributed normally. Example, there may be fat tails. Consequ ...
