Question

В результаті тестування група студентів набрала наступні бали: 3; 4; 3; 5; 4; 2; 2; 4; 4; 3; 5; 2; 4; 5; 4; 3; 4; 3; 3; 4Проранжувати вибірку. Знайти моду, медіану, розмах і середнєзначення.

Answer 1

Ответ:

Пошаговое объяснение:

2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5

Мода - значение, встречающееся чаще всего , т.е 4

Медиана - значение в середине набора данных, т.е 4

Размах - разность между максимальным и минимальным значениями переменных , т.е 5-2 = 3

Среднее значение: сумма всех чисел / кол-во чисел, т.е 71/20= 3,55

Answer 2

Ranking the Data

The given scores are: 3, 4, 3, 5, 4, 2, 2, 4, 4, 3, 5, 2, 4, 5, 4, 3, 4, 3, 3, 4.

Mode

The mode is the value that appears most frequently in a data set. In this case, the mode of the given scores is 4.

Median

The median is the middle value of a data set when it is ordered from least to greatest. If there are two middle values, the median is the average of those two values. To find the median, the data set needs to be arranged in ascending order: 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5. The median is 3.5.

Range

The range is the difference between the highest and lowest values in a data set. In this case, the range of the given scores is 3 (5 - 2).

Mean (Average)

The mean, or average, is calculated by adding up all the values and then dividing by the total number of values. The mean of the given scores is 3.55.

These calculations are based on the provided data and the mathematical formulas for mode, median, range, and mean.
