How does the experimental result differ from the theoretical in terms of accuracy?
Provided that the correct model is used, the theoretical probability is correct. The experimental probability tends towards the theoretical value as the number of trials increases.

What else can I help you with?
What is the experimental probability that the next toss and spin will result in 3 and tails?
The experimental probability, by definition, can only be determined after you have carried out the experiment!
How would you compare theoretical probability and experimental probability for getting three heads to the theoretical probability. would you expect the probabilities to be equal .?
I'm going to assume you're looking for the probability of getting three heads out of three coin spins and that you're using a fair coin. For coin spins, theoretical probability is very simple. The probability of getting three heads in a row is 1/2 * 1/2 * 1/2 = 1/8. This means that if you tossed a coin three times, you'd expect to see three heads once every 8 trials. For experimental probability you need to define clear trials, for this experiment you can't just spin a coin over and over and count the number of times you see three heads in a row, for example, if you threw the following: H T H H T T H H H H H T T H T T T you have three cases where you have three heads in a row, but they all overlap so these are not independent trials and cannot be compared to the theoretical result. When conducting your experiment, you know that if you get a T in your trial, it doesn't matter what comes after, that trial has already failed to get three heads in a row. The trial is deemed a success if you get three heads in a row, naturally. As a result, if you threw the above sequence, you would to determine your experimental probability in the following way: H T fail H H T fail T fail H H H success H H T fail T fail H T fail T fail T fail In this example we have 8 trials and one success, therefore the experimental probability is 1/8. The sample variance (look it up), however is also 1/8, meaning that all you really know is that the experimental probability could be anywhere between 0 and 1/4. The only way to get the variance down (and therefore reduce your confidence interval) is to perform more and more trials. It's unlikely for the theoretical probability and experimental probability to be EXACTLY the same but the more trials you do, the more the experimental probability will converge on the theoretical probability.
What is an example of Empirical Probability?
Empirical means by observation, so empirical probability, or experimental probability, is the probability that is observed in a set of trials. For example, if you flip a coin ten times and get seven heads, your empirical probability is 7 in 10. This is different than the theoretical probability, which for a fair coin is 5 in 10, but that result will only be approximated by the empirical results, and then only with a larger number of trials.
How do you find the experimental probability that a particular result will occur?
You carry out the experiment a large number of times. Count the number of times it was carried out (n). Count the number of times in which the particular outcome occurred (x). Then, the experimental probability for that even is x/n.
What is the z score?
z = (x - u)/(standard dev)The z score expresses the difference of the experimental result x from the most probable result u as a number of standard deviations. The probability can then be calculated from the cumulative standard normal distribution. ie sigma(z)
Why the result is difference in theoretical and measured value?
The difference between theoretical and measured values can arise due to various factors, including experimental errors, limitations in measurement techniques, and assumptions made in the theoretical model. Environmental conditions, such as temperature and pressure variations, can also impact measurements. Additionally, simplifications in the theoretical model may overlook complexities present in real-world scenarios. These discrepancies highlight the importance of refining both theoretical frameworks and experimental methods for more accurate results.
Definition of theoretical probability?
The term "theoretical probability" is used in contrast to the term "experimental probability" to describe what the result of some trial or event should be based on math, versus what it actually is, based on running a simulation or actually performing the task. For example, the theoretical probability that a single standard coin flip results in heads is 1/2. The experimental probability in a single flip would be 1 if it returned heads, or 0 if it returned tails, since the experimental probability only counts what actually happened.
A probability found as a result of an experiment?
Probability determined as part of an experiment is called experimental probability. Probability determined by analysis of all of the possible and expected outcomes is called theoretical probability.
What does experimental value mean in chemistry?
This is the value found from actually performing some experiment, rather than the theoretical value, which is found from reference material. This could be something like 'determine the density of water'.You can look up in a reference table the density of water at a given temperature - this is the theoretical value.Now you perform the experiment. You measure the temperature, then you get a graduated cylinder and measure the mass of the empty cylinder. Now fill the cylinder with a specific amount of distilled water. Measure the mass of the filled cylinder. Subtract empty mass to get the mass of the water. Now density equals mass/volume, so divide.This value obtained from the experiment is the experimental value.
How do you find absolute discrepancy...this is different from percent discrepancy?
Absolute discrepancy is the absolute difference between an observed value and a theoretical or expected value. To find absolute discrepancy, you simply subtract the observed value from the theoretical value and take the absolute value of the result. This measurement is different from percent discrepancy, which calculates the difference as a percentage of the theoretical value.
Why do the theoretical and practical values differ?
Theoretical yield is what you have calculated to be your end result of product, usually in mass. Actual yield is what you experimentally were able to produce. Together they are used to determine percent yield.
What is the result of an experience called?
These are the experimental values.
How does accuracy and precision affect the result of an investigation?
Accuracy refers to how close a measured value is to the true value, while precision refers to how close multiple measured values are to each other. In an investigation, accuracy ensures that the results reflect the true nature of the phenomenon being studied, while precision ensures that the experimental data is reliable and reproducible. Both accuracy and precision are important for obtaining valid and meaningful results in research.
What are positive and negative controls in an experiment?
Positive controls : an experimental treatment that will give the desired result Negative controls: An experimental treatment that will NOT give the dersired result.
Why theory value is less than experiment value?
The experimental value may be either more or less than the theoretical value. Reasons for such differences:The theory may be incomplete, or a simplified version of reality. For example, you may use the ideal gas law; but real gases only behave APPROXIMATELY like the "ideal" gas. In the experiment, there may be measurement errors. Or there may be other variables, which "contaminate" the result.
Is accuracy better high or low?
Accuracy is better when it is high. High accuracy means that the measurement or result is closer to the true value or target, indicating precision and reliability. Low accuracy can result in errors and incorrect conclusions.
What is widely accepted explanation based on experimental result?
A theory is a widely accepted explanation based on experimental results.
