  • 2. Introduction
    Mc Donalds is the world’s number one fast food company.
    More than 75% of its restaurants are run by franchisees or affiliates.
    We have chosen Mc Donalds outlet situated at 3rd cross Brigade Road, Bangalore.
    This outlet is one busiest in the city.
  • 3. 1) We have considered the average product wise sales during a given 7day week
    The products taken into consideration are : Mc Veggie and McChicken Burger
    We have found out the co-relation between the two
    The tool used herein is Karl Pearson’s coefficient of Co-relation
    Formula - ∑(Xi-mean)*(Yi-mean)
    √ ∑(Xi-mean)²*√ ∑(i-mean)²

  • 4. 2) We have considered the sales data of ten consecutive days for the month of May and August
    The months are randomly picked up on the assumption that it is a good sample of the population of 12 months
    We have found the co-relation between the sales in May and August using KP’s coefficient of co-relation
    Formula - ∑(Xi-mean)*(Yi-mean)
    √ ∑(Xi-mean)²*√ ∑(Xi-mean)²

  • 5. We have also calculated mean, median and standard deviation for the sales from May and August
    Formula - ∑xi/n ,[n/2 +(n+1/2)], √ ∑(xi -mean)²/n-1

  • 6. 3 We have considered footfalls on hourly basis on a Wednesday and Saturday
    We have calculated KP coefficient of co-relation
    ∑(Xi-mean)*(Yi-mean)
    √ ∑(Xi-mean)²*√ ∑(Xi-mean)²
    We have also calculated co-relation by Spearman’s rank co-relation method
    Formula - 1- 6[∑D² +1/12(m³-m)]
    N³-N

  • 7. 4) The working hours of employees are taken
    The no. of hours worked by Raju an employee at Mc Donald’s
    He is not a permanent employee and so will be working on need basis and his work hours varies throughout the week
    His working hours for the week shows lot of variation and therefore we have calculated the coefficient of variation to determine the consistency
    Formula – Standard deviation/mean*100
    Quantsassignment.final.xlsx
  • 8. We have calculated mean, median, mode, standard deviation, variance, skewness and coefficient of variation
    Formulae –
    Median= Mean-Mode = 3(Mean-Median)
    Mean = ∑x1/n, Mode = Most no. of repeated values
    Variance = ∑(xi – mean)²/n-1
    Standard deviation= √ ∑(xi – mean)²/n-1
    Skewness = Mean – Mode/Standard deviation
    Coefficient of variation = Standard deviation/mean * 100
