If the series contains large number of items, then the process becomes tedious. Disadvantages of Median : 1 In simple series, the item values have to be arranged. We have, for instance, statistics of prices, statistics of road,accidents,statistics of crimes,statistics of births,statistics of educational institutions, etc. Median: The median is that value of the series which divides the group into two equal parts, one part comprising all values greater than the median value and the other part comprising all the values smaller than the median value.

In this sense, the word statistics is used in the singular.

Demerits of mode: Following are the various demerits of mode: 1 Uncertain and vague: - Mode is an uncertain and vague measure of the central tendency.

However, It will not be reported on your … credit report as typical mortgage would. Disadvantages of Mean Distortion Due to Extreme Values The biggest disadvantage of mean is that extreme values can result in wrong calculation of mean because suppose in the above example if 60 and pounds is replaced by 150 and 200 pounds than the mean figure of 94 pounds will be wrong as 2 extreme values has changed the whole mean figure and therefore not truly representing the correct picture about the data. Di … sadvantages: â¢ Affected by extreme values outliers The mean is the average. The standard error is essentially one estimated standard deviation of the data set for the relevant variable.

Many premium clothes aremade of a mixture of polyester and cotton to take advantage ofthese good qualities.
