I will assume the sample is random. In general, the larger the sample, the smaller the percentage error will be (the difference between percentages in the sample, and the percentages in the universe from whence the sample is taken). The percentage error tends to go down as the square root of the size of the sample.

What are scientifically valid sample?
Scientifically valid samples are those that accurately represent the population being studied, ensuring that findings can be generalized. They should be selected using appropriate sampling methods, such as random sampling, to minimize bias. Additionally, sample size must be sufficient to provide reliable and statistically significant results. Valid samples also adhere to ethical standards and maintain the integrity of the research process.
What is a group of people being studied and from which samples are taken called?
A group of people being studied is called a "population." From this population, researchers take specific subsets known as "samples" to conduct their analysis. Samples are used to draw conclusions about the larger population while minimizing time and resource expenditure. Proper sampling techniques are crucial to ensure that the results are representative and valid.
Multiply what of an experiment ensure valid results?
To ensure valid results in an experiment, it's crucial to control variables, allowing only the independent variable to change while keeping all other factors constant. Proper randomization helps eliminate bias, and using a sufficient sample size enhances the reliability of the results. Additionally, repeating the experiment can verify consistency and accuracy in findings. These practices collectively contribute to the validity and reproducibility of the experimental outcomes.
Why calculate percent error after doing an experiment?
Because then you can assess how valid your results are =D
The same experiment was conducted 6 times. How many times should the results have been similar for them to be valid?
The answers are usually always valid. What may or may not be valid are your assumptions about the underlying model. Also, the number of times the results should be similar depends on the number of possible outcomes and the variability in the outcomes. For example, if you spin a fair spinner with 12 equal segments, then the probability of similar results is less than likely.

How might choosing a small sample size affect a scientific investigation?
Statistically the results will not be scientifically valid if the sample size is too small.

Is DNA testing on blood valid after 1 year?
DNA testing can still be valid on blood samples after 1 year, but the quality and quantity of DNA may degrade over time, potentially affecting the accuracy of the results. It is recommended to use fresh samples for DNA testing to ensure the most reliable results.
What is a valid genarilation?
A valid generalization is a conclusion drawn from specific instances that is accurate and applicable to a broader context. It should be based on sufficient evidence and representative samples, allowing it to hold true in similar situations. However, it's important to recognize that generalizations can sometimes oversimplify complex realities, so they should be used with caution and updated as new information arises.
What is a valid investigation?
a valid investigation is an effective investigation i think. The results turn out to be what you had inferred.

Can I travel internationally without a valid passport or driver's license?
No, you cannot travel internationally without a valid passport. A driver's license is not sufficient for international travel.
How do scientists make sure that their results are valid?
repeated trials
What are 3 things that make experimental results valid?
booty
What accounts for the observed differences between samples?
The observed differences between samples can be attributed to various factors, including variations in environmental conditions, inherent genetic diversity, and differences in sample handling or processing techniques. Additionally, measurement errors or biases in data collection can also contribute to discrepancies. Understanding these factors is crucial for interpreting results accurately and drawing valid conclusions from the data.
Does a greek citizen need a passport to enter the UK or is id card sufficient?
A valid passport is required
