Arranging data and plots -2009
MODEL MATH-01
1. What is data? Describe the methods of collection of data with merits and demerit.
2. What is the frequency distribution? Discuss it characteristics. Describe the steps of constructing a frequency distribution.
3. What do you mean by classification, tabulation and graphical representation? Discuss the necessarily.
4. What is frequency table? Discuss the different parts of the table.
5. Explain the following: (a) Histogram (b) Ogive curve (c) Frequency curve (d) frequency polygon
6. Present the following data of the wages of 40 workers in a company are given below:
16, 18, 53, 66, 61, 60,22, 26, 25, 27, 29, 24, 31, 36, 37, 38, 49, 48, 46, 12, 15, 45, 42, 44, 45, 43, 48, 35, 38, 33, 36, 49, 46, 41, 50, 52, 59, 56, 57, 50, 63
Required:
Part 1: Construct a frequency distribution by stem and leaf diagram.
Part 2: Constructing a frequency distribution by exclusive and inclusive method.
Part 3: Constructing an absolute frequency distribution and relative frequency distribution.
Part 4: Calculate percentage frequency and frequency density.
Part 5: Calculate cumulative frequency and cumulative relative frequency distribution.
Part 7: Draw Histogram and find Mode.
Part 8: Draw frequency polygon and frequency curve
Part 9: Draw Ogive curve and hence find the Median.
Part 10: Draw less than Ogive and find the Median.
Part 11: Draw More than Ogive
Part 12: Draw an Ogive curve and hence find the limit of central 50% from the workers.
Part 13: Draw an Ogive curve and hence find the Range of central 50% from the workers.
Part 14: Draw an Ogive curve and hence find the limit of middle 20% from the workers.
Part 15: Draw an Ogive curve and hence find the Range of middle 20% from the workers.
Part 16: Draw an Ogive curve and hence find the number of worker who earned lies between tk 25 and tk 55.
Part 17: Draw an Ogive curve and hence find the number of worker who earned tk 35 and above/ more than tk 35.
Part 18: Draw an Ogive curve and hence find the number of worker who earned less than tk 45.
