Question

7. The value which appears very frequently in a data is called: *
O Mean
O Median
Mode
O Central tendency

Answer 1

The correct answer is option (c) Mode.

• Mode is one of the mean values ​​for the average trend. This number gives us a solid idea of ​​what the data set conditions are most often. For example, you know that the college offers 10 different student courses. Now, in this case, courses with the highest number of student enrollment will be counted as our data mode provided (number of students taking each course).
• Therefore, mode tells us about the highest frequency of any given item in the data set. Mode refers to the number or number that appears most in the database. Sometimes we may need to find a value, which often occurs in the database. In such cases, we get the data set mode provided.
• There may or may not be a modal value for a particular set of data. With data without repetitive values, there may be no mode at all. Also, we may obtain data with only one mode, two modes, three modes, or multiple modes. This depends on the data provided.

Answer 2

Answer:

Mode is the value that appears very frequently in a data set.

Step-by-step explanation:

• Mean : The arithmetic mean is calculated by adding the numbers of the data set and dividing the sum by the total number of numbers in the list. This is most often referred as an average.

consider the data set : 12, 34, 45, 50, 24.

Mean = (12 + 34 + 45 + 50 + 24)/5 = 165/5 = 33

• Mode : The Mode of a data set is the value that appears most frequently in a data set. Number of mode of a data set can be one , more than one  or no mode at all.

Consider the data set: 6, 8, 9, 3, 4, 6, 7, 6, 3

Here value 6 appears the most number of times i.e. 3 times.

Thus, mode = 6.

• Median : The median is the middle value in a list that is ordered from smallest to largest.

consider the data set : 4, 4, 6, 3, 2.

Arrange the data in ascending order we get : 2, 3, 4, 4, 6.

There are 5 observations and median = middle value of the list i.e. 4

• Central tendency: The tendency for the values of a random variable to cluster round its mean, mode, or median is called Central tendency.
