What else can I help you with?
How do you find the population mean for a 95 percent confidence interval?
It depends whether or not the observations are independent and on the distribution of the variable that is being measured or the sample size. You cannot simply assume that the observations are independent and that the distribution is Gaussian (Normal).
What goes on the X-axis of a frequency polygon?
The X-axis of a frequency polygon typically represents the variable being measured or categorized, such as age groups or test scores. It is a horizontal axis that shows the range of values for the variable. Each interval or category is usually evenly spaced along the X-axis to show the distribution of data points.
When calculating the mean the researcher should use data measured at which level?
interval
How is frequency distribution useful to us?
I suspect you are referring to a sample frequency distribution.Providing that the sample size is sufficiently large there are various kinds of information that can be gleaned from one:the approximate range of values in the populationthe location of the population as measured by the value that appears most often in the frequency distribution-known as its modethe likely shape of the population's distribution, in particular whether it is symmetric or skewedobviously how values of the population variable are distributedwhether there are any curious peaks or valleys, even when the sample size is largethe amount of variation around the central value
True or false the amount of alcohol consumed by a person per week will be measured on an interval scale?
true

Why are mean and mode are inappropriate to describe a data with pounds?
They can be appropriate. The answer has nothing whatsoever to do with the units of measurement: the appropriateness depends on the distribution of the variable that is being measured.
What unit is sound frequency measured in?
Frequency is measured in hertz. Cycles per second.
What is frequency of wave measured in?
It is measured in Hertz (Hz).
What Is The Difference Between Frequency and Magnitude?
Frequency refers to how often something occurs within a given time interval, typically measured in hertz (Hz). Magnitude, on the other hand, refers to the strength or level of something, often measured on a numerical scale. In the context of signals, frequency indicates how many cycles occur in a unit of time, while magnitude represents the amplitude or intensity of the signal.
Can a variable measured at the interval or ratio level can have more than one arithmetic mean?
A variable measured at the interval or ratio level can have more than one arithmetic mean.
What are the variables on a sound spectrogram and how are they measured?
A sound spectrogram measures the frequency and wavelengths of sound waves. The frequency is measured in Hertz and the wavelengths are measured in meters.
The number of cycles per second is called?
Frequency, which is measured in Hertz (Hz)
Is absolute zero point measured by interval or ratio scale?
Ratio
What is the frequency of a wave measured by?
The frequency of a wave is measured by counting the number of wave cycles that pass a fixed point in a given time period, usually measured in hertz (Hz). It represents how many times the wave repeats in one second.
Any sound with a frequency above the range humans can hear is called?
There is no such thing as a "frequency above hertz". Whatever the frequency, it will always be measured in Hertz.There is no such thing as a "frequency above hertz".
