Statistics in Business QNT/275 January 12‚ 2015 Kim Gravelle Statistics in Business Statistics are simply a way of gathering information from data. Learning from data is the essential use of statistics. The extraction of answers from data provides the foot print for further investigation and research.

Chapter one summary The use of statistics is research is noted in this chapter. It reveals that statistical procedure could be segregated into two section and they are descriptive and inferential. In analyzing both descriptive statistics does exactly what it says‚ it describes the set of data. The problem is presented and descriptive statistical basically describes what the data has to say about the same issue. However inferential statistics main goal is making predictions or inferences about

While Statistics can also be misused in many ways such as using not representative samples‚ small sample size‚ ambiguous averages and dispersions‚ detached facts‚ implied connections‚ wrong and misleading graphs‚ wrong use of statistical techniques‚ serious violation of assumption behind the statistical techniques and faculty surveys‚ we should also realize that Statistical literacy is not a skill that is widely accepted as necessary in education. Therefore a lot of misuse of statistics

techniques can be used to analyze nominal level data to describe variables‚ examine relationships among variables‚ and determine differences between groups in distribution-free or non-normally distributed samples. The assumptions of nonparametric statistics are: (1) values from measurement of study variables need not be normally distributed in the sample‚ and (2) the level of measurement of study variables is usually nominal or ordinal. The mode is the only measure of central tendency that can be calculated
