Difference between histogram and frequency polygon?
They are the same thing except that in a histogram you are using bars (like in a bar chart) to show the frequency, while a polygon uses points connected by straight lines The way I have the students do it is to plot the x,y coordinates for your data ( x is the value of the random variable, y is the frequency ) If you are doing a frequency polygon, you just connect the dots with straight lines (you need to start at zero to the left of your first point and to the right of your last point) If you are doing a histogram, just draw bars where the middle of each bar comes up to the x,y point
Is year is a ratio scale?
The year is interval scale (no natural zero); your age is ratio.
What is the meaning of a relative frequency of 0?
Relative frequency of an event is the frequency of that event divided by the total number of observations. Therefore, a relative frequency of 0 implies the event has zero proportion (or probability).
What level of measurement is the amount of gasoline pumped by a filling station during a day nominal ordinal interval ratio?
It is ratio; it has a natural zero and is numerical data.
What is the difference between interval data analysis and ratio data analysis?
Data comes in various sizes and shapes. Two of them are Interval and Ratio. Interval is a measurement where the difference between two values is meaningful and follows a linear scale. For example: in physics, temperature 0.0 on either F or C does not mean 'no temperature'; in biology, a pH of 0.0 does not mean 'no acidity'. Interval data is continuous data where differences are interpretable, ordered, and constant scale, but there is no 'natural' zero. Ratio is the relation in degree or number between two similar things or a relationship between two quantities, ordered, constant scale, with natural zero. Ratio data is interpretable. Ratio data has a natural zero. A good example is birth weight in kg. The distinctions between interval and ratio data are slight. Certain specialized statistics, such as a geometric mean and a coefficient of variation can only be applied to ratio data.
What is the number of values that lie in an interval?
The number of values that lie in an interval depends on the specific range and how it is defined. Generally, it can vary from zero values to an infinite number of values within the interval.
Why frequency of DC current is zero?
frequency if it will not zero then we cant tell its dc ...AnswerFrequency is the number of alternations per unit time. As d.c. doesn't alternate, then zero divided by any quantity of time is zero!

If the average velocity of a duck is zero in a given time interval what can you say about the displacement of the duck for that interval?
If the average velocity of a duck is zero in a given time interval, then you can say that the displacement of the duck for that interval is also zero. This means that the duck has not moved from its starting position during that time period.
How can a class frequency be equal to zero?
How can a class frequency be equal to zero?
Is it true that a continuous function that is never zero on an interval never changes sign on that interval?
Yes.
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero reexplain and cite an example?
Yes, it is possible for the average velocity of an object to be zero during a given interval even if its average velocity for the first half of the interval is not zero. This can occur when the object moves in opposite directions such that the distances traveled cancel out over the entire interval. For example, if an object moves 3 meters to the right and then 3 meters to the left in equal times, its average velocity for the entire interval would be zero.
What are the ratings and certificates for Frequency Zero - 2002?

What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
What should the beat frequency of two in-tune instruments be?
