Include the following in your frequency table: Class Intervals, Tally, Frequency, Class Boundaries, Cumulative Frequency Less Than and Cumulative Frequency Greater Than. 2. Determine the mean, median, mode and standard deviation of this raw (ungrouped) data set. V. For the following data set, complete the table and determine the mean, median, mode and standard deviation, rounded off to two decimal places. Note: Round off the to two decimal places before proceeding to mean (m – x). Write on the last two columns every digit that would appear in your calculator. 1. The following given data set is the ages of 40 residents in Brgy. 634 Sta. Mesa Manila. C.I f fm cf < т — х (т — х)? (m – x)2 m 55 – 59 3 50 – 54 45 – 49 7 40 – 44 35 – 39 30 – 34 25 – 29 5 2. In a study of the time in minutes it takes an untrained mouse to run a maze, a researcher recorded these data in seconds. C.I f fm cf < (т — х)2 (m – x)2 m 5.6 – 6.2 4.9 – 5.5 16 4.2 – 4.8 14 3.5 – 4.1 12 2.8 – 3.4 7 2.1 – 2.7 5
