make a frequency distribution of the following series 1,2,2,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7
Answers
Step-by-step explanation:
Given :-
1,2,2,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7
To find :-
Frequency Distribution Table
Solution :-
Given observations of the data are :
1,2,2,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7
Heighest value = 7
Lowest value = 1
Range = Heighest value - Lowest value
=> Range = 7-1 = 6
We use tally marks for constructing the frequency distribution table .
For grouped data
No.of classes = Range/Size of the class
provided information : -
★ make a frequency distribution of the following series
★ 1,2,2,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7
TO FIND :-
★ frequency table = ?
USING CONCEPT :-
★ to find range highest value - lowest value
Understanding the concept :
Concept :-
★ here the question is telling about data handling we have provided the series 1,2,2,3,3,3,3,3,4,4,44,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7 first we have to make a frequently table in table we have towrite class, tally marks , frequency we have to do in tally marks also
what is data handling ?
★ data handling: DATA = the word data means information and the word
★ HANDLING = means collecting. so, data handling means collecting information.
★ We know that data is a collection of observations. Visual representation of data will help us to understand it better and remember the facts easily. The word 'data' means collection of information in the form of numerical figures, or a set of given facts.
For example :-
★ when a survey is taken in a locality regarding the preference of TV programmes. The obtained data can be organized in a systematic manner so that one can find the favourite or most popular TV programmes.
QUESTION :-
★ make a frequency distribution of the following series 1,2,2,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7
SOLUTION :
series we have :
★ 1,2,2,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,6,6,6,6,7,7
★ big number = 7
★ small number = 1
so, we will minus 7 with 1 we get :
★ 7 - 1 = 6
ADDITIONAL INFORMATION :
what is range ?
Ans = The difference between the highest and lowest values of a data is called range of data.
what is mean ?
Ans = The mean is the mathematical average of a set of two or more numbers. The arithmetic mean and the geometric mean are two types of mean that can be calculated. Summing the numbers in a set and dividing by the total number gives you the arithmetic mean.
what is median ?
Ans = Median is that value which divides a series into two equal parts, one part comprising all values greater than and the other values less than the median. It is the middle value of the series when arranged in ascending or descending order.
M = { N +1 /2}
M = Median
N = Number of series
