HOW TO Convert Text Data Corpus or Content to Dataframe using CountVectorizer DrAGates
This video shows three examples for how to convert text data into a Python pandas dataframe. Example 1 is a small hard-coded corpus. Example 2 is a small hard-coded content list. Example 3 is a dynamic method that uses the OS to convert any corpus with any number of text files into a Python pandas dataframe.

Excel is the devil lol
Thanks 🥹😊🤩
very clear! thank you!
that computer fan putting in work. lol
good job
Thank you so much for the useful video, but I want to ask something, do you know how to make a scatterplot for the Spearman correlations?
The textbook states nominal or ordinal variables ONLY apply to qualitative, and continuous or discrete ONLY apply to quantitative - but this video applies continuous and discrete to qualitative. Assuming the textbook was updated after this video was made?
It is true 👍🏼 her voice helped me understand easily. Great video, indeed! Thank you!
YOU ARE LEGEND
Question - you list "height of a person" as ratio, but a person can't be zero inches high? And ratio is supposed to have a true zero possible.
Dr. Gates, thanks for your content it really made me like statistics even though I struggle with math. If my childhood was easier I assure you I would have Ace the class.
Thank you!!!
Thank you from SNHU, online, southeast PA
Very cool for this visual learner. Thanks!
🔔
youre the best Prof Amy
Thank you professor this is very helpful to me
Bravo
Its 2023, best video I have come across that summarizes the T-tests. Awesome. I am ready for my exam
You presented the three types of t-tests in simplified form. Thank you.
Great job
Thank you so so much, your tutorial really helped me so much
Thank you!
thank you .. mam ... i have watched many video for that purpose but this is gem .....thank u mam again.....
👍
Really clean and crisp. Great examples and demonstration. Thank you indeed. Helped me a lot.
Dr. Gates is an extraordinary teacher who knows how to teach. Thank you, Dr. Gates. I wish you were my statistics teacher.
nothing than heaven bleesing our one and only lecturer
I am happy to have known you and subscribed your channel three years ago. Your explanations and examples are just amazing. Your pace is very attractive
I found it helpful. 😊Thank you very much
Prof with due respect its shallow.you explained it as if spss is giving you everything.nothing was coming from your understanding
I got a chuckle out of "The r squared value is just R, Squared.
This is not two sample t test.
Thank you! This video is amazing
Thank you too much also
What is the B values that are accompanied with regression analysis ?
You saved my day🙏
I’m confused. In my textbook it says that histogram lines need to be touching or connected because it is quantitative and the width of bars have meaning. Whereas, with a bar graph, the bars do not need to touch since the width of the bars have no special meaning. In your histogram, the bars were not touching. What does this mean?
You are an extraordinary instructor. You make difficult.., easier. Keep up the good work.
After watching these videos I feel privileged that so much knowledge is out there with no price tag. A very big thank you to Dr. Ami Gates. I have learned so much from you.
Is there a place to get the data set file used in this video?
I am pretty sure that the ANOVA and the t-test are incorrect. They are done on summarized data rather than the original sample data. Notice that low number of degrees of freedom. You have more than five observations of students who studied 3 hours - it is just there are only five distinct values of scores that end up in the pivot table. Sadly, I don't think there is an easy way to perform ANOVA and t-tests using pivot tables.
Hello Dr. Gates, I am not sure if you will reply me here. However, I wanted to ask you if instead of taking squares of all the individual distances, why can we not take the absolute values of each individual distances and then take the mean of all the individual values. When I did this for the above dataset in the video, I got a std deviation( may be this is not a correct word for this), of 10.75 which is lower than the regular standard deviation of 13.26. I will try to google my question. Thanks!
Good clear explanation. Would be really nice to download the slides!
I learned even more than I was looking for. Thanks!
The table is not that clear
Thank you,very informative
Very easy explanation for learners, thanks.
Hi Dr Ami Gates. Thank you very much for this tutorial. i was stuck on this part for 3 weeks try to find solution everywhere i didn't get any help. Now i'm ready solving that problem i have with t-test. So once again thank you very much :).
For performance in a group, how should the initial mean between the final one?
