Why is it important to carry out a large number of observations in experiments?

You are required to carry out large number of observations in experiments because during experiments errors are very common. So to minimize the error, you take a mean (average) of large number of observations so that you can get a more precise value.

∙ 8y agoA single measure is subject to measurement error or even coming across a rare event on your first trial. It is important to carry out a large number of observations in an experiment because, according to the Central Limit Theorem, whatever the underlying distribution of the variable being measured, the mean of a number of observations will approach the Normal distribution with the mean which is the true value of the variable and a standard deviation (a measure of spread) which reduces with the [square root of the] number of observations. So, not only do you get a more accurate estimate of the true value but you are then also able to use statistical tests on the variable using a wide range of properties of the Normal distribution. For example, you can derive a 95% confidence interval (or any other percentage) - a range of values such that you can be 95% sure the true value of the variable is in.

Where do you put the carry in Lattice Multiplication?
Put it on the next number, and add them carry to the number.
What is the Importance of statistics in physics?
The most obvious answer runs as follows:Understanding the physical world, from large scale processes (e.g., the orbit of planets around the sun), to small scale processes (e.g., the behavior of sub-atomic particles) involves experimentation. The experiments physicists carry out produce data, and statistics is required to make sense of the data. Usually results are inductive. The physicist can use the observations in the experiment to make general statements about the nature of the universe (this is called "inferential" statistics).-- Dave
What does reverse the digits mean?
you just carry the first number and add 5 to the second number
How do you identify the number of terms in an equation?
Carry out all the multiplications and divisions and then count them.
What number is the end of the numbers?
numbers are infinite! If you can find a number, you can always add 1 to it and carry on. The numbers we don't even have a name!!
What first hand enquiry can you carry out?
You can gather information firsthand by conducting interviews, observations, surveys, or experiments. This allows you to collect data directly from the source, providing you with reliable and accurate information for your research or investigation.
