This week in #mktgfiasco4000 I read this article www.business-science.io/business/202... which gave some valid reasons on using R for business.

This week we are beginning our marketing competition and we created our teams of 4 in #mktgfiasco4000. I'm excited to see how this competition goes and hopefully my team wins!

This week in #mktgfiasco4000 we started using dummy variables in regression models. I am familiar with using excel to create these models but now I am able to do it with R markdown☺️

This week, I found a textbook that helped me create and interpret many different graphs that will help me with data analysis in R Studio: Practical Data Science with R, Second Edition by Nina Zumel and John Mount. #mktgfiasco4000

I need to learn to not just trust averages. It neeeds to be backed up with a test. Welch’s test reminded me that results can look different by chance, so always check. #mktgfiasco4000

Boxplots made more sense after practice. 😎 They show not just the average but also how spread out the data is. Ad type 1 had higher sales but more variation. #mktgfiasco4000

This week I finally understood the difference between t-test and Welch’s t-test. Student’s assumes equal variances, Welch’s doesn’t. Welch is safer in real life since groups usually spread out differently. #mktgfiasco4000 🫡

After learning about the DataCamp Certificate Courses, I am ready to take the opportunity to learn more foundational skills in the upcoming week. I am keen to explore more of R and possibly Python and even an Intro to AI Agents. #mktgfiasco4000

This week centered on t-tests, more specifically Welch's T-Test and A/B Testing. Through the videos and references, I have familiarized myself with the importance of forming effective statistical data analysis and interpreting the results in visual and explanatory means. #mktgfiasco4000

Boxplots helped me understand sales data in a simple way. I could quickly see which group had higher variation and outliers. Data visualization really makes decision making easier. #mktgfiasco4000

Learning about A/B testing this week showed me that even when we think we “know” the right answer, data can prove us wrong. Testing is more reliable than assumptions. #mktgfiasco4000

By examining mean sales and data distribution, I could see that family-themed ads were performing better from the start. This reinforces that combining basic descriptive insights with inferential tests makes for a stronger, more complete conclusion. #mktgfiasco4000

From this exercise, I learned how to apply Welch’s t-test to compare two groups with unequal variance. Using R and real data helped me see why p-values matter in decision-making. #mktgfiasco4000

This week I also learned how histograms help show the distribution of sales data. Unlike Boxplots, they give a clearer picture of how values are spread across ranges. Seeing the shape of the data made it easier to understand patterns and compare groups visually. #mktgfiasco4000

Boxplots turned out to be a simple but powerful tool. They show differences between groups quickly, making it easier to spot trends in sales data. I like how visuals and statistics work together. It made me realize how important it is to combine numbers with pictures. #mktgfiasco4000

This week I learned how Welch's t-test helps when two groups have different variances, making it more reliable than the standard t-test. It was eye-opening to see how this applies in marketing, where real data is rarely perfect. Statistics really guides smarter decisions. #mktgfiasco4000

Our professor required us to watch this video on A/B Testing. I liked the message that the failures of your hypothesis will help you learn and succeed. This is a great takeaway from this video! youtu.be/VQpQ0YHSfqM?... #mktgfiasco4000

Week 4 update in #mktgfiasco4000 : Using R to create a t-test is way easier than Excel 👁️👄👁️. I'm surprised because I've only ever used Excel, but still getting used to R, so knock on wood.
