Question

Ученик на экзаменах набрал следующие баллы : 4,3 ;5,0; 3,0 и 4,1. Найдите средний балл ученика . Чему равно среднее статестическое ( медиана) в этом ряду?

Answer 1

Средний балл 4,1 просто складываешь все баллы и делишь на их количество тут (4,3+5+3+4,1)/4

Answer 2

Средний бал (4,3+5+3+4,1)/4=4,1
Медиана равна (4,1+4,3) /2=4,2

Answer 3

Calculating the Average and Median Scores

To find the average score of the student, we can sum up all the scores and then divide by the total number of scores. The median is the middle value in a list of numbers when the numbers are ordered from least to greatest. If there is an even number of observations, then the median is the average of the two middle numbers.

Let's calculate the average and median scores:

Average Score: The student's scores are 4.3, 5.0, 3.0, and 4.1. To find the average, we add these scores together and then divide by the total number of scores (4).

4.3 + 5.0 + 3.0 + 4.1 = 16.4 Average = 16.4 / 4 = 4.1

Median: To find the median, we first need to order the scores from least to greatest: 3.0, 4.1, 4.3, 5.0. Since there are an even number of observations (4), the median will be the average of the two middle numbers, which are 4.1 and 4.3.

Median = (4.1 + 4.3) / 2 = 4.2
