Question

СРОЧНО!Зарплата руководителя отдела компании составляет 70000 руб., зарплата трех его заместителей- по 50000 руб., а зарплата 20 рядовых сотрудников отдела- по 25000 руб. в месяц. Найдите среднее арифметическое, медиану и моду зарплат всех сотрудников данного отдела компании.

Answer 1

Мода ряда- это наиболее часто встречающееся значение ряда - 25000
медиана - значение находящееся в середине ряда, при четном числе среднее двух значений
(25000+25000)/2=25000
(70000+3*50000+20*25000)/24=25000

Answer 2

Calculating Average, Median, and Mode Salaries

The average, median, and mode salaries for the employees in the department can be calculated based on the given information.

Average Salary: To find the average salary, we sum up all the salaries and then divide by the total number of employees.

Total Salary = (1 * 70000) + (3 * 50000) + (20 * 25000) = 70000 + 150000 + 500000 = 720000 Total Number of Employees = 1 (manager) + 3 (deputies) + 20 (staff) = 24

Average Salary = Total Salary / Total Number of Employees = 720000 / 24 = 30000

Median Salary: To find the median salary, we arrange all the salaries in ascending order and find the middle value. Since there are 24 employees, the median will be the average of the 12th and 13th salaries when arranged in ascending order.

The salaries in ascending order: 25000, 25000, 25000, ..., 25000, 50000, 50000, 50000, 70000 Median Salary = (25000 + 25000) / 2 = 25000

Mode Salary: The mode is the value that appears most frequently in the data set. In this case, the mode salary is 25000, as it is the most common salary among the 24 employees.

Therefore, the mode salary is 25000.

In summary, the average salary of all employees in the department is 30000, the median salary is 25000, and the mode salary is 25000.
