Histogram Definition and 59 Threads

I am a little confused about a histogram of force measurements. I was asked for my physics lab to state what the vertical axis and horizontal axis represent for a histogram of force measurements? the physics lab consists of pulling a wooden block with a force sensor to record the tension...

Hey folks, I am trying to write a paper and my suprevisor told me to make baseline measurments of the two groups and plot a histogram for each group and include that in my results. Problem is, I don't know that purpose of this histogram is and I don't know what to write. I mean yeah histogram...

Hi. I am new to using Mathematica v7 and would like to know how to generate a very simple histogram. The data is: data = {1.5, 2, 0, 0.5, 1, 2, 1.5, 3, 0, 0.5, 1, 2, 2, 3, 3.5, 0, 1, 4, 2, 0.5, 1, 0, 2, 1.5, 0, 1.5} I can generate the histogram using Histogram[data] but how do I set...

Homework Statement You have run an experiment and generated a histogram. Suppose you had 853 counts in the bin centered at 1.60, and 2,439 counts in the bin centered at 1.85. If you were to repeat this experiment (by measuring the same source for the same time period, delta t) you know...

Hello! I have a question. When I am provided with a histogram, with % of molecules along the y-axis and speed range (m/s) along the x-axis, how do I use this to determine the average speed (v avg) and v-rms (root mean square) of the molecules in the gas? I am very puzzled. Any suggestions or...

Hi, I have trouble understanding the convergence of empirical histogram to probability histogram and the convergence of empirical histogram to normal curve. It was written in my lecture notes that as the number of repetitions goes large, empirical histogram converges to probability...

Ok, I need to take the data: D1 D2 6.5 3 6 4 6.7 5.5 7 3.8 6.3 4.5 8.6 5.8 5.5 4 7 3.5 7 4.5 7 5 6.5 4 6.8 3.2 7 3.6 6 4.5 6 2.8 and make a histogram (centered around 0 -- i.e. 0 will not be an edge of a bin) of the data...

I have a quick question regarding a stats problem in my girlfriend's text. It is pretty easy I suppose, but I am not quite sure; the text does not appear to give a "general form" of how to obtain the info. Feel free to correct me if I misuse words here, I am not familiar with the stats lingo...

I am looking at values of a sinusoid, y = A sin(2*Pi*f*t), oscillating between A and -A at a frequency of 25 Hz over 0.650 milliseconds. If I find the histogram of the sinusoid, is this the same thing as the probability density function of that sinusoid? If this is not the case, what does...
