Question

Найти моду и медиану выборки 1,3,7,12,18,22,27,33

Answer 1

Т.к все числа встречаются в данном ряду только по одному разу, то моды у ряда нет.

Т.к в ряду четное кол-во чисел, то медиана ряда равна  среднему арифметическому двух чисел, записанных посередине ряда. Т.е: (12+18):2= 15

Answer 2

Finding the Mode and Median of a Sample

To find the mode and median of a sample, we first need to understand what these terms mean.

Mode: The mode is the value that appears most frequently in a dataset. In other words, it is the value that occurs with the highest frequency.

Median: The median is the middle value of a dataset when it is arranged in ascending or descending order. If there is an even number of values, the median is the average of the two middle values.

Now let's find the mode and median of the given sample: 1, 3, 7, 12, 18, 22, 27, 33.

Finding the Mode

To find the mode, we need to determine which value appears most frequently in the sample. In this case, there are no repeated values, so there is no mode.

Finding the Median

To find the median, we arrange the sample in ascending order: 1, 3, 7, 12, 18, 22, 27, 33.

Since there are 8 values in the sample, the median will be the average of the two middle values. In this case, the two middle values are 12 and 18. Therefore, the median is (12 + 18) / 2 = 15.

So, the mode of the sample is not applicable, and the median is 15.
