## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following bar graph shows the production of table fans in a factory during one week. Study the bar graph and answer the given questions. 1. The average production of table fans in that week is :

1. On the basis of given graph in question ,
Sum of production of table fans = 260 + 540 + 360 + 120 + 200 + 320 = 1800
Number of days = 6

 Required average = Sum of production of table fans Number of days

 Required average = 260 + 540 + 360 + 120 + 200 + 320 6

##### Correct Option: C

On the basis of given graph in question ,
Sum of production of table fans = 260 + 540 + 360 + 120 + 200 + 320 = 1800
Number of days = 6

 Required average = Sum of production of table fans Number of days

 Required average = 260 + 540 + 360 + 120 + 200 + 320 6

 Required average = 1800 = 300 6

1. The maximum production exceeds the minimum production by :

1. As per the given bar graph , we see
Maximum production = 540
Minimum production = 120
Required difference = Maximum production - Minimum production

##### Correct Option: B

As per the given bar graph , we see
Maximum production = 540
Minimum production = 120
Required difference = Maximum production - Minimum production
Required difference = 540 – 120 = 420

Direction: The bar-chart is showing the number of accidents in a city during the first six month of a year. Examine the bar chart and answer the following questions. 1. Percentage of decrease in the number of accidents from May to June is :

1. On the basis of given graph in question ,
The number of accidents in May = 35
The number of accidents in June = 27
Decrease = 35 - 27 = 8

 Required percent = Decrease × 100 The number of accidents in May

 Required percent = 8 × 100 = 160 35 7

##### Correct Option: C

On the basis of given graph in question ,
The number of accidents in May = 35
The number of accidents in June = 27
Decrease = 35 - 27 = 8

 Required percent = Decrease × 100 The number of accidents in May

 Required percent = 8 × 100 = 160 35 7

 Required percent = 22 6 % 7

1. By what number, is the number of accidents that occurred in April is greater than the average number of accidents that occurred during the 6 months period?

1. According to given bar graph , we have
Total number of accidents = 25 + 19 + 30 + 43 + 35 + 27 = 179
Number of months = 6

 Average Number of accidents = Total number of accidents = 29.83 Number of months

 Average Number of accidents = 179 = 29.83 6

Number of accidents in April = 43

##### Correct Option: A

According to given bar graph , we have
Total number of accidents = 25 + 19 + 30 + 43 + 35 + 27 = 179
Number of months = 6

 Average Number of accidents = Total number of accidents = 29.83 Number of months

 Average Number of accidents = 179 = 29.83 6

Number of accidents in April = 43
∴ Required answer = 43 – 29.83 = 13.17

1. Compared to the month of January, what is the percentage of decrease in accidents in the month of February?

1. On the basis of given graph in question ,
Accidents in the month of February = 19
Accidents in the month of January = 25
Decrease in accidents = 25 - 19 = 6

 Required percent = Decrease in accidents × 100 Accidents in the month of January

##### Correct Option: B

On the basis of given graph in question ,
Accidents in the month of February = 19
Accidents in the month of January = 25
Decrease in accidents = 25 - 19 = 6

 Required percent = Decrease in accidents × 100 Accidents in the month of January

 Required percent = 6 × 100 = 24% 25
