Why you obtain data?
When you collect data is when you are trying to figure something out. Say you are doing an experiment. You would want to collect data so that you could see the results of the experiment. Why you want to collect data is so that you can see your results of whatever you are doing, whether it is an experiment or an inquiry.
Give methods by which bacterial growth can be measured?
There are different methods for different bacteria, but some good general means are: perform a bacterial growth curve experiment, plate them on an agar plate, or grow them in a liquid media. T urbidity can be used to estimate bacterial growth in liquid, a Petroff-Hauser chamber can be a great tool for counting bacteria in a small amount (this can be expanded to estimate the amount in a larger volume) or you could dilute the original sample enough to count on a single slide and then use reverse dilution equations to obtain an estimate of the original sample.

Which fact about gold could not be discovered in Rutherford's experiment?
There are a few things that are true about gold that could not be discovered in Rutherford's experiment. There are solid atoms in the region that are called Nucleus.
What will happen if a crucible containing a sample is heated with a very hot flame causing the sample to splatter out in a chemistry experiment?
The experimenter could get burned by the hot or caustic sample.
Would the reported molarity of the vinegar sample be affected by an error in weighing?
Yes, you could possibly have errors in your data about the molarity of a vinegar sample during a titration experiment if there was an error made during weighing.

How could determine the concentration of ascorbic acid in an unknown sample?
The concentration of ascorbic acid in an unknown sample can be obtain by conducting a few steps by using the DCPIP test. Firstly, we must obtain the volume (dm ) of the sample solution which are required to turn the DCPIP solution (blue) colour into colourless. After obtaining the volume we use an electronic balance to obtain the mass of the sample solution in gram (g). Then we use the concentration formula of [mass (g) of solute per volume (dm ) of solution] to find out the concentration. Hence. The concentration obtained was the concentration of ascorbic acid.
In statistics which is better large sample size or small sample size?
Generally, the larger the sample the more reliable the results. Example: If you flipped a coin twice and got heads both times you could say the coined is biased towards heads. However, if you repeat the experiment 100 times your results will be a lot more reliable.

How do you think you could select a random sample of your classmates?
It depends on the what the sample is for, but at least get both girls and boys in the sample.

What is the sample size for a population of 60010?
well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.
