independently in statistics‚ discrete geometry‚ political science and optimization. The motivation and the necessity in statistics to generalize the median and the rank is very natural‚ as the mean is not considered to be a robust measure of central location. It is enough to place one outlier to change the mean. In contrast‚ the median in one dimension is very robust as half of the observations need to be changed to corrupt the value of the median. In nonparametric statistics‚ several data depth

characteristic of statistics. ANSWER 1 Various characteristics of statistics as summarized as under : 1. Statistics deals with an aggregate of facts. A single figure cannot be analyzed. 2. Statistics gets affected to a great extent by multiplicity of causes The Statistics of the yield of a crop is the result of several factors‚ such as the fertility of soil‚ amount of rainfall‚ the quality of seed used‚ the quality and quantity of fertilizer used. 3. Statistics are numerically expressed

in more than one treatment. Note that I’m using the word "treatment" to refer to levels of the independent variable‚ rather than "group". It’s probably always better to use the word "treatment"‚ as opposed to group. The term "group" can be very misleading when you are using a within-subjects design because the same "group" of people is often in more than one treatment. As an example of a within-subjects design‚ let’s say that we are interested in the effect of different types of exercise on memory

to use statistics in your research This chapter explains the importance of statistics‚ and why you need to use statistics to analyse your data. What is statistics? Put simply‚ statistics is a range of procedures for gathering‚ organising‚ analysing and presenting quantitative data. ‘Data’ is the term for facts that have been obtained and subsequently recorded‚ and‚ for statisticians‚ ‘data’ usually refers to quantitative data that are numbers. Essentially therefore‚ statistics is a scientific

SIWES was established by industrial training fund (ITF) in 1973 to solve the problem of lack of adequate practical skills‚ in preparation for employment in industries by Nigeria graduates. The SIWES program runs in the Nigeria universities in conjunction

Invariance considerations imply the MANOVA statistic should be a measure of magnitude of the singular value decomposition of this matrix product‚ but there is no unique choice owing to the multi-dimensional nature of the alternative hypothesis.
