STATISTICS PROJECT Priya Mariam Simon Aparna Rajeev Sudhit Sethi Jinto Antony Kurian
Objective The main objective of our project is to acquire in-depth understanding of collection, organization and interpretation of numerical facts for taking managerial decisions. The data for the project has been collected from the Outlook (India) site. We have referred the link for the top 100 engineering colleges in India. Here the variables used are Nominal variables, Ordinal variables and some other variables. Nominal variables used are Name of the Institution, City and G/P (Government/Private). The ordinal variable used is Rank. We have also used various other variables such as IC (Intellectual Capital), I&F (Infrastructure and Facilities), PS (Pedagogic Systems), II (Industry Interface) and P (Placement).

IC (Intellectual Capital) represents quality of students each institute possesses. I&F (Infrastructure and Facilities) include land, building and various other facilities which an institute possesses. PS (Pedagogic Systems) refer to instructional methods used for educational purposes. II (Industry Interface) means corporate interaction with the college. P (Placements) refer to campus recruitments

MeanMedianModeS.D In the above data, all the values cluster around Similarly one half of the observations in the above data is less than or equal to and 65.1 is the value that occurs with the greatest frequency have been computed by taking the positive square root of variance.
The Histogram above shows each separate class in the distribution. It shows how the frequency is distributed among the various classes. It is also easy to compare the difference between each class. For example in the above histogram, we have 5 elements in the class between 55 to 60.
Frequency Polygon Frequency Polygon shows the outline of the data pattern more clearly.
Less than ogive The Ogive curve above is a graphical representation of the cumulative frequency distribution. The X axis here represents the TOTAL obtained from various attributes and Y axis represents the cumulative frequency. At any given point in the ogive curve, we can determine the number of values lying under it.
Pie Chart showing distribution of Engineering Institutes From the above pie chart, we can infer the distribution of the type to which the college belongs. Here in our data, we have two types; private colleges which constitute 40% and government colleges constitute 60% of the total
Table showing Correlation and Regression between IC & P correlation 0.81 slope0.57 intercept0.71 R^ R
The above chart shows a high positive correlation between IC & P. This is a straight line (linear) regression model and is expressed with respect to the parameters Intellectual Capital and Placement as y=0.5707x R2= indicates the proportion of the variance in the placements which is explained by the independent variable (intellectual capital). The coefficient of correlation is found by using the above equation, and is which shows there’s a HIGH degree of correlation between the two parameters considered here.
Table showing Correlation and Regression between II & P Correlation coefficient Slope Intercept r^ r
The above chart shows that there is substantial correlation between Industry Interface and Placement. This is also a straight line (linear) regression model and is expressed with respect to the parameters Industry Interface and Placement as: y=0.854x R2=0.397 indicates the proportion of variance between the Placements (dependent variable) which is explained by the independent variable (Industry Interface). ). The coefficient of correlation is found by using the above equation, and is which shows there’s a SUBSTANTIAL degree of correlation between the two parameters considered here.

Where the sum of the squares of the differences of the rank are taken. Since we have repetitive ranks, a modified formulae is used which is shown in the above tabular column. Using this approach the Rank Correlation is found to be.9101
