how to find cumulative relative frequency

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..

Which of the following statement(s) is/are false? I. Data such as blood types (A, B, AB, O) can be organised into a categorical frequency distribution. II. Except for rounding errors, relative frequencies should add up to 100. III. A statistical device used in explorat..

Relatives - The words who, which, where and whose are called relatives which give us information about a person or thing and help us to convey two-different ideas in a well-connected wa..

A relation R is a non-empty sub-set of a cartesian product. 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 sets. If R is a relation, write x R y or (x, ..
