When to use a histogram?
Histograms are relatively similar to line plots; A bar graph of a frequency distribution in which the widths of the bars are proportional to the classes into which the variable has been divided and the heights of the bars are proportional to the class frequencies.noun
What is cumulative frequency distribution?
The cumulative frequency of a random variable X for the value x is the number of observations such that X ? x.
What is a frequency table?
A frequency table is a way of tabulating data, where the independent variable (that is, what you are measuring, such as height or length) is listed in the left hand column. The frequency, which is the number of times the independent variable occurs, goes on the right hand column. Sometimes, we represent the frequency by means of tally marks. A grouped frequency table groups the independent variable into "classes": e.g. 0 - 5, 6 - 10, 11 - 15...
Do stem-and-leaf plots show frequency?
Yes, a stem-and-leaf plot shows the frequency distribution of a variable.
How do you describe a frequency Table?
It is a table that summarises data for a number of observations on a variable. For each value (or range of values) that the variable takes the table shows the number of instances in which the variable took that value.
Which variable is directly proportional to frequency?
The variable that is directly proportional to frequency is the pitch of a sound wave. This means that as frequency increases, pitch also increases.
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.
What is the difference of directly proportional and inverse proportional?
In a directly proportional relationship, as one variable increases, the other variable also increases at a constant rate. In an inverse proportional relationship, as one variable increases, the other variable decreases at a constant rate.
What is the energy in a photon of light proportional to?
The energy in a photon of light is proportional to its frequency, according to the equation E=hf, where E is energy, h is the Planck constant, and f is frequency. This means that photons with higher frequencies have higher energy levels.
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.
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 musical term pitch most directly proportional to?
Pitch is most directly proportional to the frequency of a sound wave. A higher frequency corresponds to a higher pitch, and a lower frequency corresponds to a lower pitch.
Is inductive reactance directly or inversely proportional to frequency?
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.
Which variable is directly porportional to frequency?
energy
How does energy related to frequency?
The photon energy is directly proportional to its frequency: Energy = Planck's constant * frequency.
Are energy and frequency directly or indirectly proportional?
Energy and frequency are directly proportional. This means that as the frequency of a wave increases, the energy of the wave also increases. This relationship is described by the equation E = h * f, where E is energy, h is Planck's constant, and f is frequency.
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.
