Sum of all frequencies = 7 + 4 + 10 + 8 + 5 + 6 + 7 + 9 = 56
Total number of all frequencies = 8
Mean = 56 / 8 = 7
b) Mode
Mode the most recurring number; for the data given, the mode is 7 as it is recurring two times.
Question 8
Total number of people = 120 men + 80 women = 200
Total number of people who said yes in fraction = 8 / 10 men + “x” women = 3 / 5
Total = 3 / 5 = 60%
200 * 60% = 120
Men = 8 / 10 = 80%
120 * 80% = 96
Women = 120 – 96 = 24
Total number of women who said yes in fraction = 24 / 80 = 3/10

statistics by the way of Microsoft Excel software application. The first function used is Mean;
this function can identify the average age of all 11 students which are considered in the analysis.
The mean of age 11 students is 27 years with a standard deviation of 3. The function of standard
deviation is used to analyse the variance from which all the values of the variable are deviated
from its mean. So, it can be said that the average age of a student is 27 with +- of 3.
Another Excel function used to analyse “age” variable is maximum, this variable allows
returning the maximum value in the dataset. The Excel formula to calculate “maximum” is
“=max”. The maximum age is calculated as 35 which means, any student from the 11 selected
ones can only aged 35 or less. Lastly, the function of minimum is used to calculate the minimum
age of the students. Then formula which is used to calculate minimum value in Excel is “=min”.
The above attached table represents that the minimum age of the 11 students is 24. These values
of maximum and minimum represents that the age of 11 students is between the ranges of 24 to
35.
SnapChat – This variable is the time spend (in minutes) by each student using the social
media platform of Snapchat. The Excel function of mean, standard deviation, maximum and
minimum is used to analyse this step. The first function is mean and the formula of this function
is “=average”. Using this formula mean time spend on Snapchat has been calculated which is 38
minutes. This implies that on an average every student spends 38 minutes using and browsing
Snapchat. Another Excel function used for this variable is Standard deviation and it’s excel
formula is “=STDEV”. Using this formula, the standard deviation for the variable Snapchat is
23.16. Besides this, two other variable which are minimum and maximum are also used. The
minimum value of this variable is 0 which means out of the 11 students, there are few which do
not use Snapchat at all. The frequency table shows that these students who do not use Snapchat
are Linda and Dylan. The maximum value of this variable is 75 minutes, which means the
maximum time spend on this application by a student is 75.
Instagram – Similar to Snapchat, Instagram is also a social media interaction platform
which is quite popular these days due to which this platform is selected to be analysed. Instagram
variable is also analysed using 4 excel functions and their results are attached in the table above.
The first excel function is mean and the average time spend by a student on Instagram is 42
minutes. This time is higher than the Snapchat time which means the application of Instagram is
8
this function can identify the average age of all 11 students which are considered in the analysis.
The mean of age 11 students is 27 years with a standard deviation of 3. The function of standard
deviation is used to analyse the variance from which all the values of the variable are deviated
from its mean. So, it can be said that the average age of a student is 27 with +- of 3.
Another Excel function used to analyse “age” variable is maximum, this variable allows
returning the maximum value in the dataset. The Excel formula to calculate “maximum” is
“=max”. The maximum age is calculated as 35 which means, any student from the 11 selected
ones can only aged 35 or less. Lastly, the function of minimum is used to calculate the minimum
age of the students. Then formula which is used to calculate minimum value in Excel is “=min”.
The above attached table represents that the minimum age of the 11 students is 24. These values
of maximum and minimum represents that the age of 11 students is between the ranges of 24 to
35.
SnapChat – This variable is the time spend (in minutes) by each student using the social
media platform of Snapchat. The Excel function of mean, standard deviation, maximum and
minimum is used to analyse this step. The first function is mean and the formula of this function
is “=average”. Using this formula mean time spend on Snapchat has been calculated which is 38
minutes. This implies that on an average every student spends 38 minutes using and browsing
Snapchat. Another Excel function used for this variable is Standard deviation and it’s excel
formula is “=STDEV”. Using this formula, the standard deviation for the variable Snapchat is
23.16. Besides this, two other variable which are minimum and maximum are also used. The
minimum value of this variable is 0 which means out of the 11 students, there are few which do
not use Snapchat at all. The frequency table shows that these students who do not use Snapchat
are Linda and Dylan. The maximum value of this variable is 75 minutes, which means the
maximum time spend on this application by a student is 75.
Instagram – Similar to Snapchat, Instagram is also a social media interaction platform
which is quite popular these days due to which this platform is selected to be analysed. Instagram
variable is also analysed using 4 excel functions and their results are attached in the table above.
The first excel function is mean and the average time spend by a student on Instagram is 42
minutes. This time is higher than the Snapchat time which means the application of Instagram is
8
more popular among students than Snapchat. The standard deviation of this variable is 23
minutes which is similar to Snpachat.
The minimum time spend by a student on Instagram is 0 which means there are few
students among the 11, who do not use Instagram at all. The maximum time spend on this social
media platform is 95 minutes which means there are students two prefer to use Instagram for one
and a half hour in a day. This time is highest time spending on any social media platform.
Facebook – This is also a social media platform which is analysed same 4 excel
functions. The mean or average time spend by every student among 11 students on Facebook is
27 minutes. This time is lower than the above applications of Instagram and Snapchat which
means this application is not that famous than above applications among these 11 university
students. These 27 minutes is with a standard variance or deviation of 18 minutes.
The minimum and maximum value for the variable of Facebook is 0 and 60 which means
the time spent by every individual on Facebook is under the range of 0 to 60. This also implies
that are few students who does not use Facebook at all.
Twitter – For this variable, the four excel functions are used to analyse the popularity of
this social media platform by analysing the time spend on this platform by 11 university students.
The mean time spend on this application is 10 minutes which is least when compared to above
applications of Snapchat, Instagram and Facebook. This mean time of 10 minutes is along with
the standard deviation of 11 minutes. The minimum and maximum time spend by a student on
this application is 0 and 40 minutes. This implies that in case of Twitter as well, there are few
students who do not use this social media platform at all.
From the above descriptive analysis and its interpretation, few important insights are
gained which are:
Instagram is the most used social media platform and twitter is the least used social
media platform.
There are few students which do not use some of the social media platforms at all but at
least one application is used by every student among the 11 students.

The software application of Microsoft Excel is used to develop a scatter plot diagram
from the data of time spend by each of the 11 students on two social media platforms which are
Snap Chat and Instagram. The reason behind selecting the data of these two platforms is to
identify whether there is any significant correlation between Snap Chat and Instagram users. The
scatter plot developed for this data is attached below.
The above scatter plot is developed along with a trendline which is used to plot the value
of R square on the graph. This value of R square is used further to calculate the correlation
coeficient. By using the Excel formula of “=sqrt(number)”, the value of correlation coefficient is
calculated.
= SQRT(0.5588)
= 0.747529264
The correlation coefficient for Instagram and Snapchat is 0.747. The laws of correlation
coefficient stataes that if the coefficient is less than .3, then there is a psoitive but insignificant or
negligible relationship between the variables. If the correlation coefficient is between .5 and .7,
then there is an average but significant relationship between the variables and if the correlation
coeffcient is more than .7, then there is strong and significant relationship between the variables.
As it can be seen that the correlation coefficient for Instagram and Snapchat is 0.74, it can be
said that there is a similarity between the users of Instagram and Snapchat.
