In equation form what is the Cumulative Frequency Function for a histogram and what does it mean?
mi= summation (mj) is the equation and it means that it counts all the observations together. * * * * * Clear as mud! Suppose you have a variable X that can take the values xi and that x1<x2< ... < xn. And you have a frequency distribution function f(xi) = mi for each value of i Then the cumulative frequency distribution is F(xk) = f(x1)+f(x2) + ... +f(xk) = m1+m2+...mk that is, F(xk) is the sum of all the frequencies up to and including k. In other words, it is the number of times (frequency) that the result was less than or equal to xk.
What does 0 mean in a graph?
It is the point of origin of the x and y axes of the graph
What is the top of a graph called?
What do you mean by "top of the graph"? Do you mean the highest value? The top of the graph is called "the top of the graph" There's no term for it.
How do solve the frequency distribution?
The answer will depend on what you mean by "solve". Find the mean, median, mode, variance, standard error, standard deviation, quartiles, deciles, percentiles, cumulative distribution, goodness of fit to some distribution etc. The question needs to be a bit more specific than "solve".

What does a cumulative relative frequency of .4 mean?
If the cumulative relative frequency when the variable X takes the value x, it means that 0.4 (or 40%) of the values of the variable X are less than or equal to x.
What do you mean by 3 dB cutoff frequency?
3db frequency is the frequency at which the value in the graph is reduced by 3db level It's also known as the half-power point.

What does line plot mean?
A line plot is used to organize data while it is being collected. It is a type of graph that uses a number line to show the frequency of data.

How do you calculate the mean of data in a tally?
You times the midpoint by the frequency to get about the right number. Then add all of that together. Then divide it by however many classes you have.
