Project 2

Ques 2 : The White wine data size is more compared to red wine White wine -> 4899 rows Red wine -> 1600 rows.

Ques 3 : No null values. Both wines data is checked.

Ques 4 : Checked and found so many duplicates are there and removed in both wine data.

Ques 6 : For white wine mean density is 0.994133. For Red wine mean density is 0.9986.

Ques 8 : No null values.

Ques 9 : No outliers.

Ques 10 : By looking into the details, we can see that good quality wines have higher levels of alcohol an average, have a lower volalite acidity an average, higher levels of sulphates an average, and higher levels of residual sugar on average. Based on our data YES.

Ques 13 : So,in this data set, the number of independent variables would be 11( fixed acidity, volalite acidity, citric acid, residual acid, chlorides, free sulfur dioxide, total sulfur dioxide, density, pH, sulphates, alcohol) as these variables can potentially influence or predict the outcome of the dependent variable "quality".

Ques 16 : White wine is more quality than red wine.

Ques 17 : Let's calculate the alcohol content less than median 9.4, 9.8, 10.3, 11.2, 8.8, 10.8, 12.1. The median alcohol content is 9.4.

Ques 19 : The relationship between the residual sugar content and the quality rating of wine is not necessarily straightforward, as there are many factors that can affect the overall quality and taste of a wine.Some people may prefer sweeter wines and rate them higher, while others may prefer drier wines and rate them higher.
