Understanding Line Graphs and Box Plots: FIA 0304 Statistics Assignment

Exploring Line Graphs

A line  graph uses points connected by  line segments fromleft to right to demonstrate changes  in value.  Very  often,  the  horizontal  axis  is  used  to  plot  the  time  increments,  and  the  vertical  axis  is used to plot the value  of the variable that we are measuring. When we combineseveral variables having the same range of values in same axes, we have multiple-line graphs.You need to dosome study/ research on multiple-line graphand answer the following questions.(1)Figure 1below is a multiple-line graph that illustrates a growing business with a problem. The manager  presents  the  net  revenue,  expenses  and  net  income  in  the  graph  belowfor  the company boardto focus the business discussion on the right issueOct/ Nov2020AssignmentFIA 0304 StatisticsBy Goh YS Suki1FIA 0304 StatisticsAssignmentName: :1.This assignment carries 20%.  2.Answer all the questions in A4 size  paperswith  pen (except sketching),  put it .pdffile, and submit it via Blackboard.3.Write  yourname  on  top  of  every  page  of  your  work.Your  submission  is  expected  to  be neat, tidy and complete.4.Due date of submission: As stated in the Blackboard.5.Any late submission will get deduction of 5%.Part AA line  graph uses points connected by  line segments fromleft to right to demonstrate changes  in value.  Very  often,  the  horizontal  axis  is  used  to  plot  the  time  increments,  and  the  vertical  axis  is used to plot the value  of the variable that we are measuring.

Part BCompare  with  histogram, box  plotusually  do  a  better  job  when  we  compare  different  data  set. Abox  plot  (also  called  box  and  whisker  plot)  displays the five-number  summaryof  a  set  of  data, offer an  ideal balance  of  information and simplicity, hiding the details while displaying the  overall summary information. You need to do some study/ research on box plot and answer the following questions
