INTRODUCTION
Data forecasting is a process of predicting future data values by analysing present values.
This process involves scaling and transformation of data as well (Wang, Wang and Zhang,
2018). The main aim of developing this report is to develop an understanding about data analysis
for which the data for phone calls made in each days for 10 consecutive days is collected which
is then analysed using various techniques involving tabular and graphical representation along
with descriptive analysis and forecast analysis.
MAIN BODY
Tabular data representation
The collected data is represented below using a vertical table having 2 columns and 11
rows.
Date Phone calls made each day
10-Aug-20 15
11-Aug-20 17
12-Aug-20 20
13-Aug-20 25
14-Aug-20 22
15-Aug-20 26
16-Aug-20 28
17-Aug-20 29
18-Aug-20 21
19-Aug-20 30
Graphical data representation
The collected data is now represented using two types of graphs which are bar graph and
area chart. These charts are developed by using a software application of Microsoft Excel.
