Create a cumulative frequency (less than type) table from the given data and draw an ogive on graph paper. | Class Interval | 0–10 | 10–20 | 20–30 | |----------------|------|-------|-------| | Frequency | 1 | 6 | 15 | | Class Interval | 30–40 | 40–50 | 50–60 | 60–70 | |----------------|--------|--------|--------|--------| | Frequency | 20 | 15 | 6 | 1 |

Q.Create a cumulative frequency (less than type) table from the given data and draw an ogive on graph paper. | Class Interval | 0–10 | 10–20 | 20–30 | |----------------|------|-------|-------| | Frequency | 1 | 6 | 15 | | Class Interval | 30–40 | 40–50 | 50–60 | 60–70 | |----------------|--------|--------|--------|--------| | Frequency | 20 | 15 | 6 | 1 |

Let's first create the less-than cumulative frequency table: | Class | Less-than Cumulative Frequency | |--------------|-------------------------------| | Less than 10 | 1 | | Less than 20 | 7 | | Less than 30 | 22 | | Less than 40 | 42 | | Less than 50 | 57 | | Less than 60 | 63 | | Less than 70 | 64 | Taking the length of one side of the smallest square along the x-axis as 2 units, and similarly one side along the y-axis as 2 units, we plot the points: (10,1), (20,7), (30,22), (40,42), (50,57), (60,63), and (70,64). Connecting these points gives the less-than type ogive.
