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.
Is frequency proportional to distance?
No, frequency is not directly proportional to distance. The frequency of a wave is determined by its source and is not directly related to the distance it travels. However, factors such as the medium through which the wave travels can affect its frequency.
What is the energy in a photon of light proportional to?
The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
Is it True Or False The Period of the wave is directly proportional to its frequency?
True. The period of a wave is inversely proportional to its frequency. That means as the frequency of a wave increases, the period of the wave decreases proportionally.
What is the proportional between frequency and wavelength?
The relationship between frequency and wavelength is inversely proportional. This means that as the frequency of a wave increases, its wavelength decreases, and vice versa. Mathematically, this relationship can be expressed as: frequency = speed of light / wavelength.
What is A graphic representation of a frequency distribution constructed by connecting the class midpoints with lines?
This is called a frequency polygon.
What are advantages and disadvantages of frequency polygon?
A frequency polygon is not very effective in displaying group data when the class sizes are not the same.
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 uses line segments connected to points directly above class midpoints values?
frequency polygon
How do you draw a cumulative frequency frequency polygon and a frequency curve?

Is temperature directly proportional to frequency?
Temperature is only sometimes directly proportional to frequency. Temperature however is not always directly proportional to frequency in all cases.
Is frequency proportional to distance?
No, frequency is not directly proportional to distance. The frequency of a wave is determined by its source and is not directly related to the distance it travels. However, factors such as the medium through which the wave travels can affect its frequency.
Which variable is directly proportional to frequency?
Frequency, when referring to waves, is directly proportional to the velocity of the wave. Frequency in inversely proportional to the wavelength.
The frequency of a wave is inversaely proportional to what?
Frequency is inversely proportional to the wavelength.Their product is always the speed of the wave.
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.
Is a wave's frequency is indirectly proportional to the energy applied?
No. Energy content of wave packet is directly proportional to the frequency.
What is the energy in a photon of light proportional to?
The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
