Where to use mean, median or mode to make a decision

Measures of average are also c completelyed measures of central tendency. Their purpose is to provide a numerical figure which may describe the level of entire distribution. For utilization let five students be awarded marks as follows. 10, 11,9,12 and 13. All these scores are different from each other but at least thither is one such score to which the rest of the scores standby or nearby. There are three measures of central tendency as follows mean, median and agency (Srivastava et al. , 1989).These are utilise at different occasions when making a decision for example when the administration of the state is requiring to collect and analyze data relate to population and material wealth of the country for the purpose of planning and finance. Mean can be used when making the instructional decisions. This can be used by a teacher to get the knowledge about the students entry behavior and background in this case the distribution should be normal meaning all the scores should be pres ent.By getting the mean of the students scores, the teacher will be able to come in the teaching technique to use according to their strengths and weaknesses. Consequently, the mean should be used when the teacher is evaluating the degree to which the objectives have to be achieved so that he/she will be able to encourage good study behavior among the students. Incase the scores are scattered the mean must be used so that all the scores are brought together to enable decision making to take place may be about the performance.Median should be used for focus decisions. Students should be guided in their vocational choices educational performance and their personal problems therefore median can be used to determine the average mover in class and can be advised accordingly. At the same time, median is used to make guidance decisions especially when a quick and good computed measure is required to provide the data about significant characteristics which can help a certain group of pe ople to understand themselves better.Mode should be used in research decisions in the sense that for any research to be carried out there must be collecting of the data on the issue at hand. After collecting the data, scoring, and analysis should be done and interpretation of the whole information given. When the information is incomplete mode must be used. It is also used when one wants to know the fashion of the most recurring measure or score.
