Question

Знайдіть середню медіану і моду-18,12,5,7,5,2,1​

Answer 1

-18 ; 12 ; 5 ; 7 ; 5 ; 2 ; 1

Среднее арифметическое - сумма всех чисел делённая на их количество :

$\frac{ - 18 + 12 + 5 + 7 + 5 + 2 + 1}{7} = \frac{32 - 18}{7} = \frac{14}{7} = 2$

Медиана - число, записанное посередине упорядоченного ряда:

- 18 ; 1 ; 2 ; 5 ; 5 ; 7 ; 12

Мода - число, которое встречается чаще всего:

5 (повторяется 2 раза, а остальные числа только 1 раз)

Answer 2

Finding the Median and Mode

To find the median and mode of the given set of numbers: -18, 12, 5, 7, 5, 2, 1, we can follow these steps:

1. Arrange the numbers in ascending order: -18, 1, 2, 5, 5, 7, 12. 2. Find the median, which is the middle value in the sorted list. In this case, the median is 5 because it is the value that separates the lower half (-18, 1, 2) from the upper half (7, 12). 3. To find the mode, we need to identify the number(s) that appear most frequently in the set. In this case, the mode is 5 because it appears twice, which is more than any other number in the set.

Therefore, the median of the given set is 5, and the mode is also 5.
