less than ogives

(i) We plot the points with coordinates having abscissae as actual lower limits and ordinates as the cumulative frequencies, (70.5, 2), (60.5, 7), (50.5, 13), (40.5, 23), (30.5, 37), (20.5, 49), (10.5, 57), (0.5, 60) are the coordinates of the points. (ii) Join the points by a smooth curve. (iii) ..

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 of constructing an ogive or cumulative f..

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..

The amount of carbohydrates (in grams) contained in a variety of fast food items is shown. Identify the ogive which represents the data. => neither Graph 1 nor Graph 2 or both 1 and 2 or Graph 1 or Graph 2..

The survey results of the ages of students in the Adult Basic Education Maths classes are shown in the bar graph. Find the median, lower quartile by constructing the ogive of the data. => 15, 44 or 25.8, 20.4 or 21, 36 or 26, 15.8..

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 plotted for the frequenci..

Select the correct statements: I. Pie graph is the best representation to show the relationship between the parts and the whole. II. Pareto chart is used to show frequencies for nominal or qualitative variables. III. Frequency polygon is another name for ogive. => all are correct or I and..

Which of the following statement(s) is/are true? I. The other name for an ogive is a frequency polygon. II. The boundaries for the class limits 8.6 - 8.8 are 8.55 - 8.85. III. A Pareto chart can be used to show the relationship between the parts and the whole. => II only or I and III only..

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 or Graph ..

An animal trainer conducted some tests on different kinds of cats to study their reaction time (in seconds) to a specific stimulus. Reaction time Number of cats (frequency) 2.3 - 2.6 6 2.7 - 3.0 2 3.1 - 3.4 10 3.5 - 3.8 8 3.9 - 4.2 4 4.3 - 4.6 12 Which of the ogives represents the data ob..
