Wow. Thank You So Much for this highly informative and so comprehensive and concise video. I was cleaning a dataset yesterday and I almost cried but watching your video makes me feel so relieved. I now know what my next step will be. Thank You.

Great presentation! My experience with Microsoft’s power query tracks all the changes that you make to a data set ! The program leaves a detailed historical transcript that can easily be Reffered to show what the actual changes that have been performed on the data!

Christine your videos never disappoints. Now I am thinking like a data analyst. You deserve an honorary award for being a data analysis advocate and promoting the analytics discipline as well as helping aspiring analysts and polishing the experienced analysts.

I think this is the best video that I've seen so far concerning the Data Cleaning process. Decomposing data cleaning step by step and providing a detailed framework it is something that I have not seen on other YouTube channels! Thank you for sharing Christine and looking forward to your next video!😄

[meghanhinton]

I absolutely loved this video!! I took notes so it took me just over an hour to turn this video into notes. I really appreciate how packed with information your videos are!

[s.a.]

Your videos are like classes the information and video format feels like an actual class🎉🎉🎉

[reuelcazaubon]

This must be the best video for data cleaning. The approach is sound.

Wow, wow, wow!! OMG, this is like having free industry-based data analyst personal coach by my side. A lot of the things you mentioned in this video were not taught when I was taking courses at college. I really appreciated it, it took me 1 hour to watch the vlog and take copious amounts of notes because I believe this will serve me well in my portfolio projects as I prepare to land my first data analyst job! Thank you so much, your videos are so helpful to a beginner data analyst like myself! ♥♥

[leijiang-pilot]

[vacationexploration]

Thank You, every time I'm learning a lot from your videos

[j.b.]

Thanks for the great content! I feel learn more real-world-practical knowledge here than on other YT channels. Thanks!

[olivetonic]

invaluable information laid out concisely here, thanks very much! The confusing part of the process is being able to convey what I do to coworkers/others in a clear way. So many of these steps I I'm on automation about and never really consciously took the time to breakdown the Why!

[gamelikofijerome]

As always, great video with practical steps and insights. Totally agree with you, as a Data Analyst you shouldn't shy away from data cleaning tasks as it's the first step to ensuring you come out with meaningful data-driven insights to your stakeholders on any level. Recently, I undertook a data cleaning and transformation task as part of the initial stages of a data analyst role for which I applied. Used pandas in jupyter notebooks for the task and made sure I numbered each stage of the process and provided comments on the functions and steps used.
Thank you Christine 👍👌
