INTRODUCTION
In the recent times, business units lay high level of emphasis on undertaking statistical
tools and techniques with the motive to summarize large data set for decision making. Statistical
techniques enable management team to analyse and present gathered data set in a meaningful
way. Now, statistical tools are widely used by the firm for making suitable decisions that makes
contribution in the attainment of goals. Moreover, without using statistical techniques it is not
possible for the management team to take profitable decision from the large data set considered
for evaluation. The present report is based on different case scenarios that will provide deeper
insight about the manner which statistical test helps in presenting meaningful results. It also
develops understanding about measures of dispersion along with its strengths and weaknesses.
Further, report also depicts how graphical presentation facilitates better understanding in relation
to data set and thereby helps in making appropriate decision about near future.

Interpretation
From the above table, it can be interpret that value of marks are scored by the students is
around 46.74 which determines that on the average basis students getting very less marks. In
addition to this, they are also getting half marks in some subjects so that it critically creates
impact on the student’s performances. With the help of proper performances, average value also
considered equal score in all subjects. Therefore, it is important to enhance values which are
around 46.74%. However, there are numbers of students also getting the score around 48. Hence,
it can be interpret that overall score can be deducted among the most students that are making
score between 45 to 50. Strength and weakness of the statistical tools determines as the follows:

Measurement of the dispersion determines as the standard deviation which develop
statistical tool that reflect on the specific variable. In this regard, deviation is very high then
variable moves in systematic manner at workplace. It could be depends on the values that are
moving very fast to calculate the specific amount. Beside this, when deviation value is very low,
it has been assumed that it is also fluctuate in the business. For instance, when sales is increasing
continuously high standard of deviation is the useful perspective that considered very good value
in the enterprise (DeGroot and Schervish, 2012). On the other hand, standard deviation is not
increasing in the fast rate so that higher standard will be maintained on the regular basis. Due to
lack of stability in business, it can be seen that value of standard deviation is around 12.82 which
is determines as the moderate value and it reflect the value of the variable deviating at high rate
of moderate. In addition to this, from the above table it can be interpret that there is main reason
which create hard and almost it is deviating at the moderate and very high. It can be interpret that
measurement of the dispersion is the most important tool that assists to create effective decisions
from the different individuals. It can be stated that measure of the dispersion is that it is

useful information. This is because, with the help of t test it can be assessed that it assists to find
useful information which create significance results in systematic manner. Beside this, ANOVA
and the analysis of the variance also used by the firms (Huber, 2011). This is because, in the
exams results will be compared with the each other on the basis of different parameter. Hence, it
can be stated that ANOVA and t test both have importance in the business to develop effective
results at workplace. With the help of identifying scored marks, it can be stated that firms can
easily identified that marks can be scored by the students in both exams are same or distinctive
from the each other.
Ways to measures association between the two different subjects
In order to measures association between the two subjects correlation analysis will be used. This
is because, mentioned tool also helps to identify that extent of the above variable also considered
relations with each other that assist to create effective functioning. Beside this, chi squire tool
also used for the analysis purposes. This is because, same correlation identify major extension.

From the above table it can stated that given data has been observed that value of the
intercept is around 7.65 and best value also determines which is around 2.15. It means that value
of the independent variable also remains constant that reflect on the creative value and
perspective. Beta value is around 2.15 which could be reflect to the changes that impact on the
variable which considered several changes in the unit. In addition to this, in the case of child who
is 7 months then the variable value will be changed around 9.155. It means that weight will be
increasing which impact on the results. Further, there is 8 month of child who has weight around
9.37. When child getting age of 9 months then in the case of the weight increasing 9.58. In
addition to this, if the different age changes requires factors that create major impact on the
changes that can be take place in the business. In this regard, there is significance develop from
the table which is around 2.15>0.05. It means that changes in age also considered big difference
not comes with the weight of the individuals. on the other hand, R considered value of multiple
which means that there is perfect correlation among the different variables and with changes in
one variable (Lee, 2012). In the correlation there are different variables exists that considered
changes with equal change and comes with different aspects. Value of the R also denotes that
0.95 is the mean which create certain changes with independent variable around the 95%.
Therefore, changes comes in the depend considered the changes which make effective results at
workplace. In respect to make certain changes which comes in the systematic manner. therefore,
it can be stated that both the variables also considered important perspective that depends on the
each other. It is also useful measurement that is needed to perform creative results at workplace.
In addition to this, it can be interpret that variables are independent in nature so that activities
