What is Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
What uses line segments connected to points directly above class midpoints values?
frequency polygon
What is the difference frequency graph versus percentage graph?
The main difference is that the vertical scale for a frequency graph is in units (or numbers) whereas in a percentage graph, it is in percentages,
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 is the difference between a cummulative frequency graph and a cumulative frequency polygon?
A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
What is a frequency polygon graph?
In a Frequency Polygon, a line graph is drawn by joining all the midpoints of the top of the bars of a histogram. A frequency polygon gives the idea about the shape of the data distribution. The two end points of a frequency polygon always lie on the x-axis.
What is five letter name for cumulative frequency polygon?
graph?
What is Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
The difference between a histogram and a frequency polygon is?
the basic difference between histogram and frequency polygon is that histogram uses bars to show its frequency and frequeny polygon uses points and join its staight line
What is a cumulative frequency polygon?
By its very nature, measuring cumulative frequency on either axis of a graph will produce a continuing line on the opposite axis. Therefore, it is impossible to construct a closed frequency polygon when dealing with cumulative frequency.
What is difference between frequency polygon and line graph?
The difference between frequency polygon and line graphs is their purpose. Frequency polygons are for understanding shapes distributions, while line graphs shows information that is related in some way.
What is a bar graph that shows the number of data items that occur within each interval?
It could be a bar graph or a frequency polygon. Or, if the intervals are of different sizes, a histogram.
What are the three basic forms of statistical presentation?
bar graph,histogram and frequency polygon are the three basic forms of statistical representation
What uses line segments connected to points directly above class midpoints values?
frequency polygon
What is the difference between simple frequency distribution and grouped frequency distribution?
frequency is the kinds of the line graph, bar graph, picture graph, pie graph. that's all
What is A graphic representation of a frequency distribution constructed by connecting the class midpoints with lines?
This is called a frequency polygon.
