Overall good, though was a little buggy. 2-3 videos didn't have a transcript. Also, the hands-on assignments were a big buggy, but that may be more of an issue caused somehow with the addition of the Coursera coach. Extra buggy, didn't give my my certificate, just the Congratulations on completing your course

My last straw was when I found the correct function for the assignment in the NEXT video, not in the one that precedes it. How did you expect me to pass it when your theory is out of order?
Moreover, this course is unnecessary for a JUNIOR Data Analyst.

Question 1
Scenario 1, questions 1-7
As part of the data science team at Gourmet Analytics, you use data analytics to advise companies in the food industry. You clean, organize, and visualize data to arrive at insights that will benefit your clients. As a member of a collaborative team, sharing your analysis with others is an important part of your job.
Your current client is Chocolate and Tea, an up-and-coming chain of cafes.
The eatery combines an extensive menu of fine teas with chocolate bars from around the world. Their diverse selection includes everything from plantain milk chocolate, to tangerine white chocolate, to dark chocolate with pistachio and fig. The encyclopedic list of chocolate bars is the basis of Chocolate and Tea’s brand appeal. Chocolate bar sales are the main driver of revenue.
Chocolate and Tea aims to serve chocolate bars that are highly rated by professional critics. They also continually adjust the menu to make sure it reflects the global diversity of chocolate production. The management team regularly updates the chocolate bar list in order to align with the latest ratings and to ensure that the list contains bars from a variety of countries.
They’ve asked you to collect and analyze data on the latest chocolate ratings. In particular, they’d like to know which countries produce the highest-rated bars of super dark chocolate (a high percentage of cocoa). This data will help them create their next chocolate bar menu.
Your team has received a dataset that features the latest ratings for thousands of chocolates from around the world. Click here to access the dataset. Given the data and the nature of the work you will do for your client, your team agrees to use R for this project.
Your supervisor asks you to write a short summary of the benefits of using R for the project. Which of the following benefits would you include in your summary? Select all that apply.
1 point

Question 2
Scenario 1, continued
Before you begin working with your data, you need to import it and save it as a data frame. To get started, you open your RStudio workspace and load all the necessary libraries and packages. You upload a .csv file containing the data to RStudio and store it in a project folder named flavors_of_cacao.csv.
You use the read_csv() function to import the data from the .csv file. Assume that the name of the data frame is flavors_df and the .csv file is in the working directory. What code chunk lets you create the data frame?
1 point

Question 3
Scenario 1, continued
Now that you’ve created a data frame, you want to find out more about how the data is organized. The data frame has hundreds of rows and lots of columns.
Assume the name of your data frame is flavors_df. What code chunk lets you review the column names in the data frame?
1 point

Question 4
Scenario 1, continued
Next, you begin to clean your data. When you check out the column headings in your data frame you notice that the first column is named Company...Maker.if.known. (Note: The period after known is part of the variable name.) For the sake of clarity and consistency, you decide to rename this column Maker (without a period at the end).
Assume the first part of your code chunk is:
flavors_df %>%
What code chunk do you add to change the column name?
1 point

Question 5
After previewing and cleaning your data, you determine what variables are most relevant to your analysis. Your main focus is on Rating, Cocoa.Percent, and Company. You decide to use the select() function to create a new data frame with only these three variables.
Assume the first part of your code is:
trimmed_flavors_df <- flavors_df %>%
Add the code chunk that lets you select the three variables.
1 RunReset
What company appears in row 1 of your tibble?

Question 6
Next, you select the basic statistics that can help your team better understand the ratings system in your data.
Assume the first part of your code is:
trimmed_flavors_df %>%
You want to use the summarize() and sd() functions to find the standard deviation of the rating for your data. Add the code chunk that lets you find the standard deviation for the variable Rating.

This must be one of the most challenging courses I've taken in this program! Not only was I a total newbie to programming languages, but I also had to rethink the way I look at data analytics as well. I always thought that data analysis only involved processing, cleaning, and analyzing the data, it never occurred to me that programming languages are involved as well. Even though it was really challenging, I really had fun learning to code, especially when it already got to coding my data viz. I realized that there are completely different tools analysts can use to achieve the same results. I am now more open and excited to learn other tools for analysis well beyond this program. The way this course was structured really helped a lot! It helped me ease into the new language, get to know it, and practice it with the activities. The hands-on activities are what I appreciate the most, not only did they guide me to what I needed to accomplish for that activity, but they also allowed me to use different functions and find out techniques I could use to make the code or my analysis more efficient. Thank you so much for your hard work!

The main female instructor was fantastic. The tools taught outstanding. However, there are two parts that need a review. The first is the idea that hiring managers prefer candidates who challenge the corporate status quo with new ideas. That may be soley with Google as I have yet to meet one in the general private sector who did. Most intereviewers are solely interested in what the candidate can produce for the firm at the time. New ideas are not part of the picture until the ones immediately pressing on the firm are resolved. The second issue was with your 'bias' button as it relates to statistical analysis. That error becamse the source of my capstone project. You have confused bias for sampling error. A store manager misjudging which film will sell well and over-ordering the wrong tapes is not a bias error but a sampling error. It is the equivalent of saying that your car has a bias for steering left due to an underinflated tire. That is a lean, not a bias.
That said. my capstone project describes real bias that has been going on in the country for decades.

This course looks at how to use programming in R to perform all of the stages in the data analysis process, from preparing and processing data, to performing preliminary and advanced analysis, to finally sharing the findings with your audience. The steps are very clearly shown with the trainer guiding you at the right pace. There are plenty of opportunities to follow along as instructed and understand the techniques by doing them - this is a great way to learn how to code. Various resources are linked to at key stages allowing for further reading on core concepts and even keeping 'cheatsheets' on key R packages for future reference. The priniciple of ongoing learning is conveyed perfectly with the instructor acknowledging her own meandering journey as an analyst and as a coder. Finally, the use of R markdown to display the steps you've used in your analysis and to easily produce a final report or presentation is extremely valuable for me. I will definitely be going through this course several times as I practice using R now and in the future. Excellent course 10/10

Excellent base knowledge for R programming aimed at data analysis delivered in an easy to follow manner and at a reasonable cost. The course not only gives the student a good start but also provides lots of accessible resources and tips to move from a novice R programmer towards mastery. Remarkably, everything worked, I write this because I have attempted to follow instructions for such things as downloading programming ide's in other online courses and found them outdated, not so here. Everything is current and up to date. I think any student with average grades in the past can work through this course, perhaps repeating sections at times, and find themselves fairly R proficient in a timely manner. Personally with two hours effort every morning while my pre-schooler was still asleep I was confidently coding in less than a month (while using an old outdated Chromebook I bought for $100, not necessary to invest thousands in a new computer).

It is not perfect, but nonetheless is still very good! In fact, this is the best course I have taken for learning (a lot of) R ever. So that's a great bonus. After the analysis and visualization courses, I was about to give up on the Google Data Analytics series because of the bad quality of those two courses. But yeah, this R course is good. The coach understands how to captivate the audience, and the course is well-paced and very informative. I learned so much from this course. In fact, here is where I actually learned the analysis and visualization steps that were supposed to be taught in the previous two courses. My recommendation is to just skim over the analysis and visualization courses, just to get a broad idea of what they offer. But really use this R course to learn analysis and visualization. Because this course actually explains the why of it all too, along with the how. So it is very effective.

I highly recommend Google's Data Analysis with R Programming course as an introduction to R. The course quickly gets one up and running quickly. I was able to install R and R Studio/Posit, learn how to navigate R Studio, install and load packages, and use R to clean, analyze, visualize, and share data analyses. I think this course would be great for an aspiring analyst with little to no experience or someone like me who is an experienced analyst wanting to learn R. You will get out of the course what you put into it. It's possible to get a rudimentary understanding of R by quickly completing only the required elements, but one thing that I appreciated is that the course points at a number of resources for further inquiry and study. You won't leave this 5 week course an expert, but there is plenty here to launch one successfully. I'm impressed with how much I learned over the 5 weeks.

This is the first time I followed a course from google & coursera. This is a most valueble course for the persons who wish to enter the data analyst career. The course content is much clear and the lecturer also explains each theorytical and practical parts clearly in a way that any one including the persons who don't have much listening skills, can understand.It is beacause the pronounciation is that much clear.
On the other hand, the quizes and lessons have been arranged in a proper sequence. Each reading supports with clear theories and relevant codes as well as other useful website links. There is a seperate glossary for each part as well. Course covers entire process of the data analysis with practical examples and more.
Finally course is great and thank you very much for the google and coursera team.
