Data Analysis And Statistics

Table , Chart or Graph for Data PresentationData aggregation , processing to decipher meaning(prenominal) conclusions and presentation form the aggregate of statistics , which is genuinely vital part of our professional life . normally , the cranky data is really weird and jumbled It is very difficult to draw any meaningful conclusions from the raw data . Therefore , the data needs to be organized in a tabular form for easy processing to draw some meaningful conclusions . Besides , the data is presented in fitting graphical form for better presentation as it is verbalize that A picture is worth thousands of words . The first clipping ever , I was given an assignment in a Mathematics divideify to collect and organized the attach obtained by my classmates in Mathematics in last year s mental test using suitable tabular format and as a map . The marks obtained by all 100 classmates of tap (including myself ) was collected . The same is presented in the appendixIt hatful be seen that the raw data is weird and it is very difficult to draw meaningful conclusions from the data . The minimum marks was 34 and the maximum marks was 97 . Therefore , the entire range was divided in 7 classes 30-40 , 40-50 , 50-60 , 60-70 , 70-80 , 80-90 and 90-100 . These classes were entered in first column . In the chip column the mid foreshadow of the mathematical group was entered . In the ternion column , the number of students falling in each class was recorded . In the class 30-40 , the students scoring marks from 30 to 39 were counted .

Those scoring 40 to 49 were counted in group 40-50 and so onThe frequency table is presented belowClass Interval Mid geological period Frequency30-40 35 540-50 45 1350-60 55 1860-70 65 1770-80 75 3180-90 85 1490-100 95 2 From this frequency table , many efficacious conclusions can be drawn some of these are listed below18 students failed in MathematicsThe mean score was calculated The tabulated data was presented as a polygon chart in figure 1 , belowThis chart was prepared using MS excel . For this the mid point of the class range was taken as x-axis and the frequency of the class interval was taken as y-axisFrom this graph it can be seen that most of the maximum number of students scores in the 70-80 rangeThus it can be concluded that from tabular and pictorial presentation it becomes very easy to grasp the data , which is otherwise very weirdAppendixMarks obtained by my classmates including myself in mathematics in last year s scrutiny .
