Draw a pie chart for the following data. Item of expenditure Food Health Clothing Education Savings Amount spent in rupees 3750 1875 1875 1200 7500

Given, Item of expenditure Food Health Clothing Education Savings Amount spent in rupees 3750 1875 1875 1200 7500 We have to draw a pie chart for the given data. A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice, is proportional to the quantity it represents. Now, Total amount spend = 3750 + 1875 + 1875 + 1200 + 7500 = 16200 . We make a table to find the angle of the sectors. The table is shown below. Item of expenditure Amount spent in rupees Ratio between expenditure and total income Angle of sector Food 3750 3750 16200 = 25 108 25 108 × 360 ° = 83 . 3 ° Health 1875 1875 16200 = 25 216 25 216 × 360 ° = 41 . 7 ° Clothing 1875 1875 16200 = 25 216 25 216 × 360 ° = 41 . 7 ° Education 1200 1200 16200 = 2 27 2 27 × 360 ° = 26 . 7 ° Savings 7500 7500 16200 = 25 54 25 54 × 360 ° = 166 . 6 ° Using Protractor, we can split a circle into five parts for the corresponding angles as obtained above. Hence, the Pie chart is drawn for the given data as above.

Draw a double bar graph for the following data. Birth and Death rates of different states in 1999 . State Birth Rate (Per 1000 ) Death Rate (Per 1000 ) Andhra Pradesh 22 8 Karnataka 22 8 Tamil Nadu 19 8 Kerala 18 6 Maharashtra 21 8 Orissa 24 11 Source: The table is taken from vital statistics SRS 1999 .

Given: Birth and Death rates of different states in 1999 . State Birth Rate (Per 1000 ) Death Rate (Per 1000 ) Andhra Pradesh 22 8 Karnataka 22 8 Tamil Nadu 19 8 Kerala 18 6 Maharashtra 21 8 Orissa 24 11 Source: The table is taken from vital statistics SRS 1999 . We have to draw a double bar graph for the given data. A bar graph is a graphical display of data using single bars of various heights. A double bar graph is a graphical display of information using two bars besides each other at various heights. We can use a double bar graph to compare two data groups. A double bar graph has two axes. Now, the double bar graph for the given data is drawn below: X-axis is considered for various States. Y-axis is considered for Birth rate and Death rate. Thus, the double bar graph for the given data is drawn.

Draw a Pie chart for the following data. Time spent by a child during a day: Time spent for Sleep School Play Others Time spent 8 hours 6 hours 2 hours 8 hours

Given, Time spent by a child during a day: Time spent for Sleep School Play Others Time spent 8 hours 6 hours 2 hours 8 hours We have to draw a Pie chart for the following data. A Pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice, is proportional to the quantity it represents. Now, Total number of hours = 8 + 6 + 2 + 8 = 24 . We make a table to find the angle of the sectors. The table is shown below. Time spent for Time spent (in hours) Angle of sector Sleep 8 8 24 × 360 ° = 120 ° School 6 6 24 × 360 ° = 90 ° Play 2 2 24 × 360 ° = 30 ° Others 8 8 24 × 360 ° = 120 ° Using Protractor, we can split a circle into four parts for the corresponding angles as obtained above. Hence, the Pie chart is drawn for the given data.
