simple frequency distribution table

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 call..

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..

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interval. This is explained by an example below. The following frequency distribution table gives t..

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..

The scores of 20 students in a quiz are collected and shown in the table: Construct a frequency distribution and a histogram for the data. => Figure - A or Figure - B..

PA = PC = A (Amplitude) The time taken for one oscillation is known as the time period (T). The number of oscillations made by the pendulum in one second is called its frequency (symbol n or f). Frequency is measured in hertz (Hz..

Find the frequency of the number 5 from the frequency table. => 1 or 5 or 8 or 6..

1. All bars have the same thickness. 2. Distance between two consecutive bars is the same. The bars can touch each other. 3. The height of each bar represents the frequency number of students. 4. The thickness has no significance. 5. Bar graphs are preferred when each item of data ..

. Thus, these pathways are also called the reflex arcs . Know Something Complex or Conditioned Reflex This type of reflex involves the brain but it is also as fast as the simple reflex. Salivation on smelling one's favourite food is an example of conditional reflex. The individual recogni..
