Question

Consider a small unit of a factory where there are 5 employees : a supervisor and four labourers. The workers earn a salary of Rs. 5,000 per month each while the supervisor gets Rs. 15,000 per month. Calculate the mean, median and mode of the salaries.​

Answer 1

Answer:

• Mean = Rs. 7000
• Mode = Rs. 5000
• Median = Rs. 5000

Step-by-step explanation:

Case (I),

▶▶Mean = (5000 + 5000 + 5000 + 5000 + 15000)/5 = 35000/5 = 7000

▶▶ Mean = Rs. 7000/-

▶▶So, the mean salary is Rs. 7000 per month

Case(II),

▶▶To obtain the median, let us arrange the salaries in ascending order:

▶▶5000, 5000, 5000, 5000, 15000

▶▶Median = (n+1)/2 = (5+1)/2 = 6/2 = 3rd observation

▶▶Median = Rs. 5000/-

Case(III),

▶▶Mode = Number of times an observation is repeated = Rs.5000/-

▶▶ Mode = Rs. 5000/-
