frequency range table

The frequency table displays the time taken by number of workers for doing a particular work. Find the range of the data. Time (in min) Frequency 15 8 20 19 25 23 30 3 35 17 40 1 => 23 or 1 or 24 or 22..

Mike made a frequency table of the scores of his students in a test. What is the total number of students whose scores are in the ranges 96 - 100 and 76 - 80? Score Frequency Below 75 3 76 - 80 13 81 - 85 4 86 - 90 9 91 - 95 3 96 - 100 1 => 15 or 16 or 14 or ..

The frequencies of ages of freshmen(fresh students) at a private university are as recorded. Age Range Percentage of Enrolment 18 - 20 40 20 - 22 25 22 - 24 15 24 - 26 20 Construct an ogive and a histogram for the data. => Graph 1, Graph 4 or Graph 1, Graph 2 or Graph 3, Graph 4..

Frequency Distribution - A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is called an arra..

The frequency distribution for the rainfall readings (millimeters) of 60 selected cities is shown. Select the percentile graph for the data. Rainfall range Number of cities 0 - 2 18 2 - 4 12 4 - 6 7 6 - 8 13 8 - 10 10 => Graph 1 or Graph 2 or both Graph 1 & Graph 2 or none of th..

The number which tells us how many times a particular data appears is called the frequency. For example, 2 marks have been scored by five students which means marks 2 occurs five times. Therefore, the frequency of score 2 is five. Similarly, the frequency of mark..

In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in both directions to meet the X - axis to..

The sound waves having frequencies less than the audible range are called infrasonic wave..

Sound waves are emitted from a vibrating source and transmitted through air. The human ear can hear sound waves in the range 20 Hz and 20 KHz. This range is known as audible range. The sound waves having frequencies above the audible range are known..
