No, continuous data can be ranked and has more possible values.
No, but binomial methods can pull out more information.
No, binomial data must be the numbers 0 or 1.
They give partial information when continuous data values are hard to get.
All of these other answers.
It allows the conversion of non-numerical data into numerical data.
A fixed number of binomial events with the outcome being the number of successes.
Converts binomial data into discrete data. Results in a histogram for calculating probability.
The number of trials (n) in the binomial experiment. The probability (p) of getting a successful outcome.
All of these other answers.
µ and σ.
𝜇 = 𝑛𝑝 𝜎 = √[𝑛𝑝(1−𝑝)]
x-value is a number, b-value is a number and an inequality sign.
To change from finding area under bars (have width) to areas under lines (no width).
Add or subtract 0.5 to start measuring area from one side of the histogram bar.
Variable Vote, contains two values of 0 and 1.
All of these other answers.
The histograms only contain two bars / can only get probability of success.
The histograms contain many bars / can get the probability of many events.
They are needed to calculate probability with the binomial equation.
To use a normal curve to approximate the area under a binomial histogram.
No, only when the binomial histogram is unimodal and symmetrical.
