Explanation of Solution
Use of Focus Group:
- Focus group refers to a team of individuals whose reactions are observed in market research or political analysis.
- In order to determine the reactions, his analysis is performed through either guided or open discussions regarding a new product.
- The focus group can gather the information about a new system which is going to be implemented very easily.
- As the group consists of members of various tiers, the result for the discussion plays an important role.
- In the focus group the members shares their valuable findings and the defects can be rectified easily.
- The result from the focus group discussion seems to be effective than the personal interview with the stakeholders...

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.

- I have a few questions I need help with Statement: When we build a nearest neighbor model, we shall not remove the redundant dummies when coding a categorical variable. True or False Statement: One reason why a neural network model often requires a significant number of data observations to train is that it often has a significant number of model parameters to estimate even if there are only a few predictors.
