@@Pl15604 I'm not sure I understand your question, but the more data you collect, the better the estimates tend to be and the more power you have to correctly reject the null hypothesis (if that is something you want do).

I know that this is the beginning of the course and maybe further it will be explained, but I will still leave a small remark. I think that in order to draw a normal distribution in this case one must normalize the data beforehand, because otherwise the fitted normal curve will suppose that negative cases exist. In this example we have 20 as a mean and 10 as a standard deviation. So we have 2.5% probability for negative values, which is impossible. Great course anyway. Listening just for fun.

Really like your videos, Josh! I am building my statistics knowledge solely with these videos. I have a question at @3:40 that how is standard deviation 10? If we are looking at how wide the curve is, it widens from 10 to 30 which makes a difference of 20 but 20 is mean. I'll probably look at the next video about calculating s.d. but curious for now.

Hi, Just stumbled upon your channel by chance while looking for something to get busy with during this pandemic. I found your videos easy to understand and I got actually hooked into watching the videos. Great Job and thanks for simplifying the concepts! By the way just a quick question though in this lesson. In the hypothetical data, you mentioned that most of the cells had between 20 to 30 mRNA transcripts, which represent the positive sigma level. May I know why you only chose the sigma level to the right? I am just quite lost with the positive and the negative sigma level. Hope you could give further clarifications on this. Thanks
@michaelgalario66553 жыл бұрын
Also, you mentioned that Standard Deviation corresponds to how wide the curve is from the mean or how spread the data is from the mean. From the example, you said it's 10, which made me think why 10? Shouldn't it be measured from the mean up to the last bin/sigma where one can see the data, which in this case is spread to 40. My understanding is from 20 to 30, it's 10 and from 30 to 40, another 10, so I assumed that it's 20.. Sorry about my question, I hope you get my point. Just got curious on this topic. Just want to have a better understanding of the concept. Thanks!
@statquest3 жыл бұрын
There are lots of ways to describe how data are spread about. One way is to use the maximum and minimum values (in this case, the maximum value is 40 and the minimum value is 0), but another method is the standard deviation. The standard deviation is useful because it corresponds to how wide a normal distribution is spread. To understand more about the normal distribution, see: kzbin.info/www/bejne/qKupiWiEjNSdppI

Or, is Population related to all events of interest that have had already happened and that we wish to analyze using statistics. But, since its to costly to gather information/mesurements regarding entire population, we gather a sample by which we estimate population parameters and approximate population curve. When we actually approximate population curve, does that mean we have a approximation Probability Distribution, or is probability distribution concept related to sample space only? If so, how do we calc. probabilities for each element of the population? Sorry for long question, but these terminologies between Probability and Statistics REALLY confuse me.

There are lots of distributions in statistics. The normal distribution is one, and there's another called the exponential distribution, and there are many more. However, all of them can be used in the same ways. If we collect a lot of data and draw a histogram, we can fit a distribution to it and use it to calculate probabilities (by calculating the area under the curve or with the histogram).

8:04 says "the new measurements will come from the same population" sounds like "come from the same distribution?" 1. How do experimenters (both the 1st and subsequent people) know what distribution the samples come from and thus what population/distribution parameters to estimate? 2. What happens when someone later proves that the samples come from some other distribution that's not normal, does that invalidate all previous experiment results? 3. Even within the same family of curves, experimenters may use different tests which have different degrees of freedom, does this cause a reproducibility problem? 4. What does it mean for an experiment to be reproducible, or to have reproduced a previous experiments? Are the estimated population parameters and their confidence intervals part of defining reproducibility?
@statquest3 жыл бұрын
Han, the good news is that all of your questions can be answered by the Central Limit Theorem. In a nutshell, it says that regardless of the underlying distributions, the means (averages) are normally distributed and this means we can use basic tests (like the t-test) to compare means regardless of the underlying distribution. For more details on the Central Limit Theorem, see: kzbin.info/www/bejne/j3LPe3Z7ea1lq7s

If the number of observations is large enough, then a binomial distribution is accurately approximated with a normal distribution. So that's what's going on here. See: en.wikipedia.org/wiki/Binomial_distribution

Is the rate equal to the tanget slope of the curve?

What time point, minutes and seconds, are you asking about?

Is there any explanation for the rate and shape parameters?
@statquest4 жыл бұрын
Different distributions have different population parameters. The normal distribution has the mean and standard deviation. Other distributions have other population parameters. For example, the Gamma distribution has rate and shape parameters. However, the concepts are the same - these population parameters determine the the properties of the population distribution.

Does it only work for features that can be ordered? (e.g. by heights, or by number of mRNA transcripts) What if we count things having different colors, for example? (like, 3 green apples, 7 red apples, 5 yellow apples, 1 rainbow apple)

The concept of population and estimated parameters applies to all kinds of data. However, when we have discrete data, like your example, we often have different parameters other than just the mean and variance.

Sir, where I can find the details about the "Central Limit Theorem"? You have mentioned in your video about it.

So, the mean and SD calculated for a sample is termed statistic? . correct me if Wrong....

The estimated mean and standard deviations are statistics.
