The removal of outliers often leads to a reduction in the variability (or variance) of the dataset as outliers are extreme values that increase variability.

A Histogram is preferred over a kernel density plot for discrete data. While kernel density plots can give a smoother representation of data, they are more suitable for continuous data. A histogram's bar-like representation suits the discrete nature of the data.

If the dataset is large and removing outliers would lead to a significant loss of data, binning could be a suitable method. In binning, the outliers are not removed but rather they are replaced with summary statistics like mean, median, etc.

Zero skewness means the distribution is symmetrical, and high kurtosis means the distribution is leptokurtic with a sharp peak and fatter tails. Therefore, the data distribution will be symmetrical but with a potential for outliers. This may affect the results of statistical tests or models that assume normality, as extreme values could have a disproportionate effect on the results.

EDA techniques can help detect multicollinearity in a dataset. By examining correlation matrices or scatter plots, we can get a sense of whether predictor variables are correlated with each other, which might indicate multicollinearity. This is an important consideration as multicollinearity can affect the interpretability of some models and can lead to unstable estimates of regression coefficients.

If a machine learning model uses distance-based methods, we need to apply Data Scaling to bring all features to the same level of magnitudes. This is because distance-based methods are sensitive to the scale of the features.

Readability is crucial in data visualization because it directly impacts the audience's ability to understand and interpret the data correctly. A readable graph communicates the data's message effectively, allows the audience to draw accurate conclusions, and makes the data accessible to a broader audience.

The logarithmic transformation is a common method used in data transformation to handle outliers. It helps in pulling in high values, which reduces skewness.

You might prefer to use multiple imputation over a simpler method like mean imputation because multiple imputation provides more accurate estimates. This is because it estimates multiple values for each missing value, reflecting the uncertainty around the true value. It also better preserves the relationships between variables.

EDA (Exploratory Data Analysis) is used to understand data patterns or trends and to formulate hypotheses, while CDA (Confirmatory Data Analysis) is applied to test those formulated hypotheses.
