1.
what is correlation?
Answer: Correlation, in the finance and investment industries, is a statistic that measures the degree to which two securities move in relation to each other. Correlations are used in advanced portfolio management, computed as the correlation coefficient, which has a value that must fall between -1.0 and +1.0.
2.
What is Regression linear?
Answer: Regression is a statistical method used in finance, investing, and other disciplines that attempts to determine the strength and character of the relationship between one dependent variable (usually denoted by Y) and a series of other variables (known as independent variables).
3.
What is data analysis?
Answer: Data analysis is a process of inspecting, cleansing, transforming and modelling data with the goal of discovering useful information, informing conclusion and supporting decision-making.
4.
Formula of Correlation
Answer: ρxy = Correlation between two variables Cov(rx, ry) = Covariance of return X and Covariance of return of Y σx = Standard deviation of X σy = Standard deviation of Y
5.
What is an Average?
Answer: A number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number

Programme: UEFA champions finance and social media
TITLE:
What is the financial report of the UEFA champions?
ABSTRACT:
The Abstract of winnings teams of the UEFA champions finance and their social
media reports such as what data they have been use. Also how they workout their
excel reports by using the methods of analysis.
INTRODUCTION:
The main goal of this study to me is that I must find out what was the remarkable
work have been done on the excel. Also needs to find the methods of the analysis I
am going to use in this assignment. The focus of this analysis is that I have to figure
out does have been changes overtime.
DATA AND METHODS:
, The Data and Methods I am going to use is the social media of the teams of the UEFA
champions and the Columns I going to do are (H,I,J,K,L,M) and the rows I choosing
are the (2,3,4,5,6,7). The method analysis I am going to use is the correlation method
of the Facebook and the Instagram of the UEFA champions teams which is the
0.9582081 if we round it up it will come up to 1. The way I find this correlation of the
Facebook and Instagram for the all teams the first thing I have done is to install the
formula of the correlation which is (=Correl (arny1, arny2). Also the regression liner
equation is (y = 0.8549x - 3.1594).
FINDINGS: the remarkable and the expected thing I have been found in this
analysis is the correlation coefficient of the Facebook and the Instagram which is the
0.9582081. Also, I have been found the Average of the Facebook, Instagram, and the
sum of the revenue. The difference I have been found is the correlation coefficient of
the Total Staff Costs and Pre-tax profit/loss which is less than the correlation
coefficient of the Facebook and Instagram. The meaning of the coefficient of
correlation indicates the strength of the connection between two variables.
When we say that two variables are correlated, it means there exists a definable
relationship between the 2 . If there's a direct correlation between the 2
variables, it means when the worth of 1 variable goes up, the worth of the
opposite goes up as well and conversely when the worth of 1 variable goes down,
