1. Arrange the following data in ascending order. (a) 7, 2, 9, 14, 0, 6, 15, 24, 8, 25 (b) 9.6, 8.1, 5.0, 3.5, 1.7, 9.3, 1.4, 0.5 2. Arrange the following data in descending order. (a) 11, 2, 0,9,6, 1, 22, 13,22,4 (b) 1.2, 3.5, 0.1, 0.3, 2.4, 8.6, 5.0, 3.7 3. Construct the frequency (ungrouped) table for each of the following. Calculate EX by using the table. (a) 4, 6, 6, 5, 2, 4, 4, 3, 6, 4, 2, 3, 2, 3, 3, 3, 4, 5, 6, 4, 2, 3, 4 (b) 8, 8,5,4,5,6,6,8,7,9,6,5,6,7,7,8,9, 8, 6, 8, 6, 6 (c) for b) calculate the proportion of scores below 6, and the proportion of scores above 7. 4. The marks obtained out of 25 students of a class in the examination are given below. 1) Represent these data in a grouped frequency table taking the class interval of 5. (Begin by arranging in descending order then create the table) 21,6, 23, 3, 1, 12, 10, 20, 13, 3, 17, 19, 11, 6, 21, 9, 6, 10, 23, 4, 5, 1, 5, 11, 24 5. Complete the table given below. Name the class limits (lower and upper limit) and the class boundaries (real lower limit, real upper limit) of the following class intervals Class Limits Class Boundaries Lower limit upper limit real lower limit real upper limit 41-50 51-60 61-70 71-80 81-90 6. Complete the chart by calculating the relative frequency, cumulative frequency and cumulative percentage of each interval.
