How do you work out the frequency for a histogram?
Frequency Density multiplied by the class width
What should a well constructed histogram reveal to you?
It should reveal the frequency density of the variable for the well-defined classes. From this, it should be easy to work out the exact frequency in each class.
Does bar graphs touch?
Everyone including books and people answering on this website get this wrong. It does matter and the rule is simple. If your horizontal access is something where it is not possible to rank in any special order- for example favourite crisp flavours or different ways of getting to work - then the bars are separate. I think spacing of a third or half the bar width looks neatest. If you have a horizontal axis of some grouped data, like length of leaves, then you have a histogram and the bars touch. Strictly a histogram has a vertical axis of density to accommodate different width groupings. In many cases all the widths are identical and you have a simple frequency up the vertical axis. There does not seem any unaminity of the correct name for this animal. On the one hand I'd use "histogram" so it's clear the bars touch but then some purists object because the vertical axis isn't density. On balance I'd still call it a histogram.
How do you work out the area of a histogram?
A histogram consists of rectangular bars. The area of each is its base times its height. Multiply these together, ensuring that you include any scale factors in your calculations.
How do you work out the mean from a histogram?
take the values from the chart and then add all the observations by total number of observation! it is good that it is not a polygon!

How hard you work your muscles is called frequency?
No, frequency is about how often.
How do you convert tones to cubic meter natural gas?
The tone, or frequency of sound depends on the density of the medium that it is travelling through. Without information about the composition of the natural gas, it temperature and pressure, it is not possible to work out its density and so the tone of sounds propagating through it.

What work do you have do in density?
divide the mass by the volume: mass/volume=density
What is the density of botato?
Potato? Density is volume/mass. Work it out yourself.
How do you work out the mass of an object with the density and the volume?
Density = (Mass) divided by (Volume) If you know the density and volume, then Mass = (Density) times (Volume)
