Question
Table 2 divides the range of these 25 schools' academic performance into nine intervals and gives some of their frequencies and relative frequencies. Based on the information provided in Table 1, use the dropdown menus to complete Table 2 Table 2 Academic Performance (Percentage of students performing at or above grade level) Frequency Relative Frequency 0.12 0.08 0.08 0 to 9 10 to 19 20 to 29 30 to 39 40 to 49 50 to 59 60 to 69 70 to 79 80 to 89 0.12 0.08 0.08 0.12 1.0 Total 25 The preceding table obeys some basic rules of grouped frequency tables . The width of each interval is a relatively First, the table has approximately 10 number. The bottom score in each class interval is a of the widthExplanation / Answer
first table is not given,not possible to complete the table 2.
First, the table has approximately 10 class. The width of each interval is a relatively simple number. The bottom score in each class interval is a multiple of the width.
In which interval would a score of 29.6 fall? 30-39 ( its limit will be 29.5-39.5)
In which interval would a score of 19.4 fall? 10-19 ( its limit will be 9.5-19.5)
Usually in the case of discrete variate, inclusive type of class intervals are used. if data are not discrete then we make inclusive class interval into exclusing by deduction 0.5 from lower limit and addition of 0.5 to upper limit,
in the above question exclusive type class interval is made. in exclusive type the class limit is such that the lower class limit is included, but the upper class limit is excluded
