How is a frequency curve in statistics different from a frequency polygon?
Mayankabu
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 Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
What is the difference between a polygon and a curve?
well a polygon has angles and a curve has none.
How many sides does the largest polygon have?
There is no mathematical limit to the number of sides that a polygon can have. As the number of sides increases the polygon will become more and more like a closed curve - a regular polygon will become like a circle. The size of the polygon and accuracy of measurement will determine when it is no longer possible to distinguish between the polygon and the curve. Nevertheless, the two shapes will be mathematically different objects.
Is a triangle with a curve a polygon?
No, all the sides of a polygon must be straight lines.
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 the difference between a polygon and a curve?
well a polygon has angles and a curve has none.
What is the difference between a concave and a convex polygon?
A concave polygon has lines that curve inwards whereas a convex polygon has lines that curve outwards and they are found on and inside spheres
What is an inscribed polygon?
A circle with a polygon in it An inscribed polygon is any polygon that can fit within a specific curve or circle.

Is a triangle with a curve a polygon?
No, all the sides of a polygon must be straight lines.
What is the opposite to a convex polygon?
An open curve, perhaps.
Can a polygon have a curve?
No. The sides MUST be straight lines.
