Your all the videos are very helpful, I'm from non-mathematics background learning data science, your videos helped me a lot. Please make more videos on these statics and mathematics of data science, which are necessary according to you.
I am studying Data Science from couple of months. Had studied many courses, but first time come to know about modified Z score on codebasics yt channel
Thank you Sir for creating the playlist on Mathematics and Statistics for Data Science and Machine Learning. It really helped understand the complex concepts. Your teaching skills are truly commendable, and your dedication doesn't go unnoticed. I have a small suggestion: could you consider adding a video on the Central Limit Theorem? Additionally, I had a question on the Modified Z score video. While I understand its use in identifying outliers, if we prefer not to remove outliers, especially when the data is accurate but includes extreme values like in this case, can we address it by applying logarithmic transformations? Thank you once again for your valuable teachings.
Great Video.., As you mentioned in the video inorder to get median the column values should be sorted, but in our excel exercise heights are not sorted we are having 6.2 after 10.0. but here it won't make any changes in the result even if its not sorted. just mentioning this here!!
Sir, I have 3 years of Java Development experience and now started learning Machine learning. I want to know whether it will be helpful in the future. I am currently working in a good product-based company and get a lot of opportunites. Now transition from software development to data field ,is it a good decision?
So what we will do if we get 3 cases in modified z score and 2 cases in normal z score. Which one will we use? Suppose take this example only what will i take ?
sir i have question if dataset contains N number of columns with numeric values for which column we need to apply the outlier technique how can we decide the column to apply the outlier technique?
Is it necessary to calculate the modified z score as greater than 3.5 only? as I have taken the whole dataset for the task and with a 3.5 value I am getting 971 outliers
can someone please tell me if this playlist is enough to get for data analyst? not data science. Is this series complete and can I rely only on this playlist?
Not sure why you’d ever want to use the mean vs the median. Even if a high value isn’t tagged as an outlier it shifts the mean. Guess you need a subject matter expert to investigate.
