Data Handling(4th Grade > Mathematics ) Questions and Answers
Explanation:-
Answer: Option B. -> 52 inches:
B
Given:
1 drop = 4 inches of rain
Number of drops on Saturday =4drops
Number of drops on Sunday =9drops
Thereforeinches of rain on Saturday and Sunday
=(4+9)×4
=13×4=52inches
Explanation:-
Answer: Option B. -> Thursday:
B
Byobserving the graph, (1 drop = 1 inch)
Rainfall recorded on Monday = 10 inches
Rainfall recorded on Tuesday = 06 inches
Rainfall recorded on Wednesday = 08 inches
Rainfall recorded on Thursday = 11 inches
Rainfall recorded on Friday = 07 inches
Rainfall recorded on Saturday = 04 inches
Rainfall recorded on Sunday = 09 inches
From above , we can see that Thursday had the heaviest rainfall.
Explanation:-
Answer: Option B. -> 2:
B
Data written vertically are called columns. Here, there are two vertical datas present under the name Item and Quantity. Thus, there are two columns present in the given table.
Explanation:-
Answer: Option C. -> 44 inches:
C
Given:
1 drop = 4 inches of rain
Rainfall recorded on Thursday = 11 drops
Therefore, the number of inches of rain on Thursday = 4×11=44inches
Explanation:-
Answer: Option B. -> 2:
B
The number of times a particular value of dataoccurs is known as frequency.
Here, in the given data set:
K, J, F,J, A, J, N, S, A, J, A, W, P, J, A, H, A, P, O, W, J, K, Z.
we observe that K is occurring twice, therefore the frequency of K is 2.
Explanation:-
Answer: Option C. -> 5:
C
The number of times a particular value of data occurs is known as frequency.
Given:
×, ×, ÷, -, ×, +, +, ÷, ×, +, -, +, +, -, ÷, ×
We observethat the '+'symbol is occurring 5 times and therefore the frequency of + is 5.
Explanation:-
Answer: Option B. -> Raw data:
B
Raw data is the data that has not been organised well enough for use.
Example:
Given below are the marks (out of 25) obtained by 10 students of class (V A) in mathematics in a test.
18, 16, 12, 10, 5, 5, 4, 19, 20, 10
Explanation:-
Answer: Option D. -> 5:
D
Arranging the data in ascending order, we get, 0,0,1,2,3,4,4,5,6,8.
On observing, there are 5 days(0,0,1,2,3) that had atemperature of less than 4° C.
Explanation:-
Answer: Option B. -> 8:
B
4, 6, 5, 5, 4, 6, 3, 3, 5, 5, 3, 5, 4, 4, 6, 7, 3, 5, 5, 7
Here, we see the number of families with3 members is 4 and with 4 members is also 4.
So, the number of families with less than 5 members is 8.
