What is utility of cumulative frequency curve?
The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.
What is Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
How is a frequency curve in statistics different from a frequency polygon?
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.
What is cumolative frequency curve?
A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.
What are the main features of Google Advertisement?
The main features of Google Advertisement include, but are not limited to, IP address exclusion, frequency capping, and placement targeted advertisements.
What is gaussian frequency curve?
The Gaussian curve is the Normal distributoin curve, the commonest (and most studied) of statistical distributions.
How do you draw a cumulative frequency frequency polygon and a frequency curve?
To draw a cumulative frequency frequency polygon, plot cumulative frequency on the y-axis and the upper boundary of each class interval on the x-axis. Then connect the points with straight line segments, starting from the x-axis at 0 cumulative frequency. For a frequency curve, plot the midpoint of each class interval on the x-axis and the frequency on the y-axis. Then connect the points smoothly with a curve to show the distribution of data.
What uses rectangles to show frequency distribution?
normal curve
Features of indifference curve?
two indifference curve never cut each other..
What is the highest point of the frequency curve?
The "frequency curves" are called waves. The highest point of a wave is the crest.
What is the area under the curve for the histogram below?
There is no histogram below.However, the area under the curve for any histogram is the total frequency.
What is an Allen curve?
An Allen curve is a graphical representation which reveals the exponential drop in frequency of communication between engineers as the distance between them increases.
