                 • The independent variable is the cause. Its value is independent of other variables in your study.
                 • The dependent variable is the effect. Its value depends on changes in the independent variable.


              Data Preprocessing

              Data preprocessing is an essential phase in the machine learning process that prepares datasets for effective
              machine learning applications. It is the process of detecting and correcting (or removing) corrupt or inaccurate
              records from a dataset. It includes multiple processes to clean, transform, reduce, integrate, and normalise data.

                       Data Processing and Data Interpretation


              Data processing means preparing and analysing raw information to train models or
              predict outcomes, including tasks like cleaning and training. Data interpretation in
              AI involves analysing model outputs to understand patterns, refine models, and make
              informed decisions.

              Observe and answer the following:
              ●  How many big  lollipops are there in the given picture?
              ●   If each large lollipop represents 5 units of sweetness, how much total sweetness do
                  the three lollipops represent?
              ●  Among the small round candies, which colour appears most frequently?

              ●  What is the ratio of pink round candies to blue round candies?

              ●  How many pink round candies are there in the image?
