Analysis of P-Value, Standard Deviation, Mean, Mode, and Median

The document provides explanations of key statistical concepts including p-value, standard deviation, mean, mode, and median. The p-value indicates the probability relative to the null hypothesis, with values less than 0.05 considered statistically significant. Standard deviation measures the spread of data around the mean. Mean, mode, and median are measures of central tendency, each with its own advantages and disadvantages in data analysis. Mean, representing the average, is effective for comparing data sets but can be influenced by extreme values. Mode identifies the most frequent value, while median represents the middle value.

The probability or P refers to the value in any research, which also indicates the value of probability
value in relation to the null hypothesis (Gerrish and Lathlean 2015). The null hypothesis refers that there
is no transformation between the population tested (Groves et al 2013). If the p value is at a lower level
then the level of p value is more likely to be the difference between the populations tested. if the value
of p=0.05 then there is 5% probability that there will be no modification between the populations
tested and in such cases you would have to gather a similar results from five out of one hundred tests
(Portney and Watkins 2014). The data, which is mentioned in the above studies, have value of p values
less than 0.05; this makes it statistically noteworthy that the statistical test is appropriate (Groves et al
2013).
Standard deviation is a number whichtells how measurements for a group are extent out from the
average (mean). A low standard of deviation indicates that most of the numbers are near to the
average, while the high deviation slandered means that the numbers are extent out
Mean, mode and median are very popular research methods, which are used in almost every business,
as well as in the computer sciences and engineering industries. Mean denotes the averageand it is
calculated by set of data divided by the number of data.
Mean indicates to the average and is calculated through data divided by the number of data. Mean is
known to prove the effectiveness of a tool when the comparison for different sets of data is done;
however, this method can be a disadvantage as well if influenced out of extreme values. Mode is the
kind of value that appears the most.
