Olympiad Test : Pictorial Representation Of Data - Class 5 MCQ

The number of sixes is given by its frequency, or how high the bar is for the score 6. So, look for 6 across the horizontal axis and then read off its frequency on the vertical axis. There were 3 sixes.

5 of them favored orange and 1 only favored green. 5 − 1 = 4 Therefore 4 more favored orange than those who favored green.

Shraddha’s best subject was English, where she scored 60. Shraddha’s worst subject was Geography, where she scored 25. Therefore she scored (60 – 25) = 35 more in her best subject than in her worst subject.

The top of the English column on the graph is mapped to the point 60 on the vertical axis.  So, Shraddha’s score for English was 60. Then, we must add 15% of 60 to 60 to get the Shubhra’s score for English. 60 + (15%) (60)
= 60 + 9 = 69.

Sleep represents 25% of Shraddha’s day. 25% of 24 hours
= ¼ × 24 hours
= 6 hours.
So the height of the bar for sleep would be 6 hours.

She spent about 8.5 hours sleeping and about 4.9 hours watching TV.

That’s about 3½ hours longer.

B is the correct answer. The recorded temperature at 8 p.m. was 35°F. The recorded temperature at 10 p.m. was 25°F. The temperature was dropping at a regular rate. Therefore at 9 p.m. the temperature was about 30°F.

From the information shown in the graph, the record remained unchanged from 1968 to 1980 - a 12 year period. (In fact it remained unchanged for nearly 15 years from October 1968 to July 1983)

The number of students greater than or equal to 60 inches tall are shown in the bars representing the groups 60 - 65, 65 - 70, 70 - 75 and 75 - 80
= 5 + 2 + 3 + 1
= 11

The number of students that were greater than or equal to 55 inches tall but less than 70 inches tall are shown in the bars representing the groups 55 - 60, 60 - 65 and 65 - 70
= 6 + 5 + 2
= 13

The number of eggs measured is found by adding the frequencies
= 1 + 8 + 17 + 40 + 26 + 8
= 100

Given histogram shows the birth weights of 100 newborn babies.

From the graph, babies who weigh more than 5lb and less than 10lb are 8 + 15 + 30 + 22 + 16 = 91.
Therefore, the percent of the babies who had neither a low or a high birth weight is  91/100 × 100 = 91%

B is the correct answer. Construct a Frequency Distribution table as follow:

The letter that occurs the most frequently is S.

The correct answer is B. Scores less than 3 means 1 or 2, and does not include 3 itself. There were 16 1’s and 18 2’s, so 34 altogether less than 3.

The correct answer is B. Scores less than 3 means 1 or 2, and does not include 3 itself. There were 16 1’s and 18 2’s, so 34 altogether less than 3.

The right answer is D. Greater than or equal to 4, but less than or equal to 7 includes 4, 5, 6 and 7.
8 students scored 4
11 students scored 5
8 students scored 6
7 students scored 7
So 8 + 11 + 8 + 7 = 34 scored greater than or equal to 4, but less than or equal to 7.

The right answer is C.  Less than 3 includes 0, 1 and 2, but does not include 3.
4 classmates had 0 pets
12 classmates had 1 pet
8 classmates had 2 pets
So, 4 + 12 + 8 = 24 had less than 3 pets.

C is the correct answer. There is a trick to this question. The table shows the number of siblings (brother and sister) each child has. The question asks how many children in the family ... which also includes the child being surveyed. So if a child has 3 siblings, then the family has 4 children!
So to find How many families had more than 4 children, we must include those children with 4, 5, 6, 7, 8 and 9 siblings:
4 of them had 4 siblings
2 of them had 5 siblings
1 of them had 6 siblings
0 of them had 7 siblings
0 of them had 8 siblings
1 of them had 9 siblings
So 4 + 2 + 1 + 0 + 0 + 1 = 8 of them came from families with more than 4 children.

B is discrete because the numbers of brothers and sisters can only be values like 0, 1, 2 etc. The other three are all continuous because they can take any value within a range, such as 160.3 cm or 75.35 kg.

B Total cars 2 + 4 + 6 + 5 + 2 = 19
