Probability and Statistics | Visualizing Grouped Data using Frequency Table and Histogram
For some data sets the number of distinct values is too large it is useful to divide the values into groupings, or class intervals, and then plot the number of data values falling in each class interval. The number of class intervals chosen should be a trade-off between (1) choosing too few classes at a cost of losing too much information about the actual data values in a class and (2) choosing too many classes, which will result in the frequencies of each class being too small for a pattern to be discernible. Although 5 to 10 class intervals are typical, the appropriate number is a subjective choice.
A bar graph plot of class data, with the bars placed adjacent to each other, is called a histogram. The vertical axis of a histogram can represent either the class frequency or the relative class frequency; in the former case the graph is called a frequency histogram and in the latter a relative frequency histogram.
A cumulative frequency plot is called an ogive.

Probability and Statistics | Confidence Interval of a Paired Comparison in ANOVA
Переглядів 3121 годину тому
ANOVA, or the analysis of variance is a hypothesis testing procedure used to deal with testing the equality of population means from different treatments. The simplest ANOVA is one-way ANOVA, which contains only one factor variable with different levels. For example, there are 6 observations taken from each of 5 populations with means μ1, μ2, . . . , μ5 , respectively. We may wish to test if th...

Thanks for the breakdown! A bit off-topic, but I wanted to ask: My OKX wallet holds some USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). Could you explain how to move them to Binance?
how should I watch your video if I am new to statistics and probability...can't understand your previous lectures are on advanced topics and newer one's such as this on the basics?? please help
this is just a live streaming with several videos combined. If you want to learn from beginning to advanced, I advise you to select the playlist 'Probability and Statistics', which has about 96 videos uploaded. From easier one such as Box Plot, to advanced topic like ANOVA in sequence.
@@statistics32thanks for your timely help😊
@@animeshmishra8869 thank you too
Please Explain Chapter 7 of the book Introduction to Statistics. Third addition by Ronalde Walpole
Videos for transformation of variables, and moments generation function have been uploaded several months ago, you can check
Sir, can you answer my question? Students take the semester exam for course A. In the exam, they are given 20 multiple choice questions, with 5 answer choices. Of the 5 choices available, there is only 1 correct answer. Based on this information, calculate: a) What is the probability that students can answer 2 questions correctly b) What is the probability that students can answer 10 questions correctly.
a) b(2,20,1/5) = 0,1369 b) b(10,20,1/5) = 0,002
Hei, you can use binomial distribution (see my video), and choose a p = 0.2 (if no more information than then problem description here), so will be easy to calculate probabilities for these two questions.
Thank u sir,im done 🙏
@@d.kosmou ok
I want to learn univariate distribution can u pls give a link to those videos ?
follow my live streaming now
@statistics32 okay thank you...
I really appreciate your efforts! Could you help me with something unrelated: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). What's the best way to send them to Binance?
Thanks for the forecast! I need some advice: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How can I transfer them to Binance?
Hi , I am a statistics major student (1st year) . I hope your channel is going to help me
first ?
not done yet

Thank you very much👏🏻
You are welcome
I am intermediate in machine learning. How could I improve myself.

Hello sir, how did you find the k value in the TI? And how did you calculate 2 values when you just found 1 value for the TI? Thank you for the video!
Got the ans ??

ничего не понял но очень интересно
maybe the explanation is too simple. Of course we can talk about Central Limit Theorem in 10 hours more. Just keep watching my videos, then you will understand more. thanks.
