Towards the end of the Course, you will be working on a live project. You can choose any of the following Problem Statements as your Project work :

Project Title: Census Data Analysis
Industry : Government Dataset
Description : Analyze the census data and predict whether the income exceeds $50K per year. Follow end to end modelling process involving:
1. Perform Exploratory Data Analysis and establish hypothesis of the data.
2. Test for Multicollinearity, handle outliers and treat missing data.
3. Create training and validation datasets using Stratified Random Sampling(SRS) of data.
4. Fit Classification model on training set (Logistic Regression/Decision Tree)
5. Perform validation of the models (ROC curve, Confusion Matrix)
6. Evaluate and freeze the final model.

Project Title: Sentiment Analysis of Twitter Data
Industry : Social Media
Description : A sports gear company is planning to brand themselves by putting their company logo on the jersey of an IPL team. We assume that any team which is more popular on twitter will give a good ROI. So, we evaluate two different teams of IPL based on their social media popularity and the team which is more popular on twitter will be chosen for brand endorsement. The data to be analyzed is streamed live from twitter and sentiment analysis is performed on the same. The final output involves a comparable visualization plot of both the teams, so that the clear winner can be seen. The following insights need to be calculated :
1. Setup connection with twitter using twitteR package. And perform authentication using handshake function.
2. Import tweets from the official twitter handle of the two teams using SearchTwitter function.
3. Prepare a sentiment function in R, which will take the arguments and find its negative or positive score.
4. Score against each tweet should be calculated.
5. Compare the scores of both the teams and visualize it.
Can I work on my own Use-Case?
Sure, you can. You can either choose one of the Use-Cases from the LearnChase Repository or create your own.

1. Introduction to Data Analytics
Learning Objectives – This module tells you what Business Analytics is and how R can play an important role in solving complex analytical problems. It tells you what is R and how it is used by the giants like Google, Facebook, Bank of America, etc.

Topics – Understand Business Analytics and R, Knowledge on the R language, community and ecosystem, Understand the use of ‘R’ in the industry, Compare R with other software in analytics, Install R and the packages useful for the course, Perform basic operations in R using command line, Learn the use of IDE R Studio and Various GUI, Use the ‘R help’ feature in R, Knowledge about the worldwide R community collaboration.

2. Introduction to R Programming
Learning Objectives – This module starts from the very basics of R programming like datatypes and functions. We present a scenario and let you think about the options to resolve it. E.g which datatype would you use to store the variable or which R function can help you in this scenario.

Topics – The various kinds of data types in R and its appropriate uses, The built-in functions in R like: seq(), cbind (), rbind(), merge(), Knowledge on the various Subsetting methods, Summarize data by using functions like: str(), class(), length(), nrow(), ncol(), Use of functions like head(), tail(), for inspecting data, Indulge in a class activity to summarize data.
3. Data Manipulation in R
Learning Objectives – In this module, we start with a sample of a dirty data set and perform Data Cleaning on it, resulting in a data set, which is ready for any analysis. Thus using and exploring the popular functions required to clean data in R.

Topics – The various steps involved in Data Cleaning, Functions used in Data Inspection, Tackling the problems faced during Data Cleaning, Uses of the functions like grepl(), grep(), sub(), Coerce the data, Uses of the apply() functions.
4. Data Import Techniques in R
