### Quants assignment

1. 1. Quants Assignment<br />By- KumariAdarsha<br />Amrita Menachery<br />Rahul Trigunayak<br />Mayank Jain<br />Rachit Nayyar<br />Shikha Jain<br />Wesley Varghese<br />Amit Nopani<br />Nitesh Kumar<br />
2. 2. Introduction<br />Mc Donalds is the world’s number one fast food company.<br />More than 75% of its restaurants are run by franchisees or affiliates.<br />We have chosen Mc Donalds outlet situated at 3rd cross Brigade Road, Bangalore.<br />This outlet is one busiest in the city. <br />
3. 3. 1) We have considered the average product wise sales during a given 7day week<br />The products taken into consideration are : Mc Veggie and McChicken Burger<br />We have found out the co-relation between the two<br />The tool used herein is Karl Pearson’s coefficient of Co-relation<br />Formula - ∑(Xi-mean)*(Yi-mean) <br /> √ ∑(Xi-mean)²*√ ∑(i-mean)²<br />Quantsassignment.final.xlsx<br />
4. 4. 2) We have considered the sales data of ten consecutive days for the month of May and August<br />The months are randomly picked up on the assumption that it is a good sample of the population of 12 months<br />We have found the co-relation between the sales in May and August using KP’s coefficient of co-relation<br />Formula - ∑(Xi-mean)*(Yi-mean) <br /> √ ∑(Xi-mean)²*√ ∑(Xi-mean)²<br />Quantsassignment.final.xlsx<br />
5. 5. We have also calculated mean, median and standard deviation for the sales from May and August<br />Formula - ∑xi/n ,[n/2 +(n+1/2)], √ ∑(xi -mean)²/n-1<br />Quantsassignment.final.xlsx<br />
6. 6. 3 We have considered footfalls on hourly basis on a Wednesday and Saturday<br />We have calculated KP coefficient of co-relation<br /> ∑(Xi-mean)*(Yi-mean) <br /> √ ∑(Xi-mean)²*√ ∑(Xi-mean)²<br />We have also calculated co-relation by Spearman’s rank co-relation method<br />Formula - 1- 6[∑D² +1/12(m³-m)]<br /> N³-N<br />Quantsassignment.final.xlsx<br />
7. 7. 4) The working hours of employees are taken<br />The no. of hours worked by Raju an employee at Mc Donald’s<br />He is not a permanent employee and so will be working on need basis and his work hours varies throughout the week<br />His working hours for the week shows lot of variation and therefore we have calculated the coefficient of variation to determine the consistency<br />Formula – Standard deviation/mean*100<br />Quantsassignment.final.xlsx<br />
8. 8. We have calculated mean, median, mode, standard deviation, variance, skewness and coefficient of variation<br />Formulae – <br />Median= Mean-Mode = 3(Mean-Median)<br /> Mean = ∑x1/n, Mode = Most no. of repeated values<br /> Variance = ∑(xi – mean)²/n-1<br /> Standard deviation= √ ∑(xi – mean)²/n-1<br />Skewness = Mean – Mode/Standard deviation<br />Coefficient of variation = Standard deviation/mean * 100<br />Quantsassignment.final.xlsx<br />
