In the Natasha Demkina experiment, the probability of correctly matching 4 out of 7 matches by chance alone is approximately 1 in 50. This level of accuracy is considered statistically significant and suggests that Demkina's claims of having X-ray vision may have some merit. However, further controlled studies would be needed to definitively prove her abilities.
You may be suffering from risk aversion, where the fear of losing is stronger than the desire to gain, leading you to prefer a small chance of success over a high chance of failure. This behavior is often influenced by emotions and perceptions of risk.
Ask him. He will either accept or decline. If he declines, that's that. If he accepts, you'll have the chance to talk with him before and during Sadie Hawkins and you will both have the opportunity to find out if you like each other. What do you have to lose?
Sampling involves selecting a subset of individuals or items from a larger population for study. Random sampling is a specific type of sampling method where each individual or item in the population has an equal chance of being selected. In random sampling, the selection of individuals is done purely by chance, reducing bias in the sample.
Yes. Otherwise they'll get deeper and deeper into it. At lease they have a fighting chance if you tell them.
It depends on your alpha level. In the social sciences, we use an alpha level of 0.05. Therefore, anything less then this is considered statistically significant. If your significance is 0.0001 it mean that there is a 1/10000 chance that you would get your results by chance alone (as the engine of change). It is therefore fairly safe to conclude that the null hypothesis is incorrect (you can conclude that your IV had a significant effect on your DV). Be careful however, when interpreting significant levels, that is not to say that your IV had a BIG or SMALL effect on your DV (this is indicated by effects size), only to say that any change that resulted is not due to chance alone.

I hope so then I can get a chance at her!

Not much chance of it. Natasha, who prefers to be called Sasha, is still considered too young for a serious relationship; her parents want her to focus on her education at this point in time.
Statistically the larger the sample size the more significant the results of the experiment are. Chance variation is ruled out.

If you repeat your experiment and obtain similar results, your experiment is referred to as being "reliable" or demonstrating "reliability." This consistency in results suggests that your findings are reproducible and not due to random chance. Such experiments contribute to the credibility of the scientific conclusions drawn from them.
