@VGF80 4 года назад

4:23 mistake: the value used at the end of that notation is supposed to be the variance (σ²) not standard deviation. Note: that I studied normal distribution in Australia.

@TranquilSeaOfMath 4 года назад

I agree it should be variance, σ². Overall, it is a very nice video, well illustrated and narrated; it is a concise overview. I especially like the definitions at the beginning to help us understand the terms statistic and parameter.

@TranquilSeaOfMath 4 года назад

@Donald Trump Good question. In this video an important idea is standard deviation; however, in further studies variance is important. It is used not only to derive the function for the normal curve, but can be used to calculate endpoints for confidence intervals and critical regions. The notation used in the video is a standard form, which means if it is not presented accurately it perpetuates errors. Using your Pythagorean example, a common error with students is that they do not take the square root after they square and sum the leg terms, meaning their formula is a^2 + b^2 = c. The square is lost in their thinking and so they have an error in their solution. Again, it is a nice video. It does well to present the real ideas they are trying to cover. Discussing a minor error without losing the rest of the topic is important too.

@sebooz4949 4 года назад

hey! Could you please prepare a video about "statistically important values" when P

@Simplelearningpro 4 года назад

Statistically important values are ones that are usually determined by the statistician or researcher. In general, a P value of 5% or lower is considered to be statistically significant. If something is statistically significant, it usually means that the relationship between two variables is caused by something other than chance. And based on that outcome, you can accept or reject the null hypothesis. I will be making a video about this topic in the future, but unfortunately not any time soon. I hope that helps! Good luck with your studies, sebo!

@ramaco_789 4 года назад

Dear Sebo statistically significant means values are statistically different but that doesn't mean it is practically significant.. www.investopedia.com/terms/s/statistically_significant.asp
