Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. In other words, it is a mathematical discipline to collect, summarize data. Also, we can say that statistics is a branch of applied mathematics
statistics intended for students in a wide variety of areas of study. Topics discussed include displaying and describing data, the normal curve, regression, probability, statistical inference, confidence intervals, and hypothesis tests with applications in the real world.
Statistics helps you learn to think like a scientist.
It can help train your mind to think about how data is organized, hypotheses, and what samples of data mean. The skill sets that you practice and apply in a statistics class can be transferred and used in many different subject areas.
Ms. D. has 12 students in her AP Statistics class. They all did very well on the final exam with scores of {81, 87, 88, 88, 88, 89, 89, 90, 90, 90, 90, 95}.
(a) The trimean is defined as Compute the trimean for the above data.
(b) The mean trimmed 50% is computed by trimming the upper 25% of the scores and the lower 25% of the scores and then computing the mean of the remaining scores. Compute the mean trimmed 50% for the above data.
