Vertical Bar Graph

1) There Are 400 Students in a School, and the School Committee Tests Their Student's IQs. They Represent the Data in the Graph. Read the Graph and Answer the Following Question:

1. The Number of Students With a High Average IQ Is:
1. 100
2. 120
3. 80
4. 50
2. The Number of Students With Borderline Impaired or Delayed IQ Is:
1. 100
2. 120
3. 80
4. 50
3. 100 Students of the School Are Present With Classification
1. Superior
2. High Average
3. Average
4. Low Average

1. We know that the range of IQ for high-average students is 110-129.
   Then from the graph, we get the range for 120 students. The correct option is option ii) 120.
2. We know that the range of IQ for high-average students is 70-79.
   Then from the graph, we get the range for 80 students. The correct option is option iii) 80.
3. From the graph, we get 100 students in the 120-129.
   Also, the classification for the range of 120-129 students is Superior.
   The correct option is the option i) Superior

2) Payel Read in Class 10. Her Mathematics Teacher Tests Their IQ in Class. The Data of Collection Is Given Below:

1. Draw the Vertical Bar Graph to Represent the Given Data.
2. Find the Total Number of Students in Payel's Class.
3. Find the Number of Students in Which Category Presents the Greatest?
4. Find the Number of Students in the High Average Category?
5. Find the Number of Students in the Low Average Category?

1.  

   

    

2. the total number of students in Payel's class is
   = 10 + 15 + 32 + 18 + 25 + 35
   = 135
   So, the total number of students in Payel's class is 135.
3. The greatest number of students present is in the range of 40-54.
   And the classification for that range is Moderately impaired or
   Delayed.
   So, the greatest number of students present in the category moderately impaired or delayed.
4. We know that the range for the high average category is 110-119.
   And from the table, the number of students we get from 110-119 is 10.
   So, the number of high-average students is 10.
5. We know that the range for the low average category is 80-89.
   And from the table, the number of students we get from 80-89 is 32.
   So, the number of low-average students is 32.
