cumulative relative frequency formula

A plot of the cumulative frequency against the upper class boundary with the points joined by line segments. Any continuous cumulative frequency curve, including a cumulative frequency polygon, is called an ogive. There are two ways ..

Cumulative Frequency Distribution - 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 ..

There are two ways of constructing an ogive or cumulative frequency curve. (Ogive is pronounced as O-jive). The curve is usually of 'S' shape. We illustrate both methods by examples given below: Draw a 'less than' ogive curve for the following dat..

When the double bonds are present between successive carbon atoms such dienes are called cumulated dienes or allenes. For example:..

Identify the incorrect statement. I. The histogram is a graph that displays the data by using continuous vertical bars of various heights to represent the frequencies of classes. II. The frequency polygon is a graph that displays the data by using lines that connect points plott..

Intensity of sound depends on its frequency. The human ear is more sensitive to the middle part of the audible range. Thus, a sound of a frequency in the middle of the audible range will appear to be louder than the sound of a frequency near the extremities of the ran..

Which among the following statement(s) is/are true about histograms? I. Midpoints are useful in determining class widths and class boundaries. II. Histograms are useful in displaying cumulative frequencies. III. Histograms are used to display categorical data. IV. Histograms are..

If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b..

A relation R is a non-empty sub-set of a cartesian product. A relation is a set of ordered pairs, i.e., R A x B where A and B are two non-empty set..

Consider the following sentences:Consider the following sentences: 42 is a multiple of 6. Line l is parallel to line m. 10 is greater than 7. In each case the first element is related to the last element by the relation in italics. The two elements named are members of two separ..
