Questions and Answers

1.

The techniques are the data which data scientist use in their day to day activities.
- A.
  
  True
- B.
  
  False
- C.
  
  Partly true
- D.
  
  I don't know
Correct Answer
A. True

Explanation
The statement is true because data scientists rely on various techniques in their daily work. These techniques include data collection, data cleaning, data analysis, data visualization, machine learning algorithms, statistical modeling, and more. By applying these techniques, data scientists are able to extract valuable insights and make data-driven decisions. Therefore, it can be concluded that the techniques are indeed used by data scientists in their day-to-day activities.

Statistical learning is accurately assessing the performance of a method.
- A.
  
  True
- B.
  
  False
- C.
  
  Partly true
- D.
  
  None of the above
Correct Answer
A. True

Explanation
Statistical learning involves accurately evaluating the performance of a method. This means that statistical learning is able to effectively assess how well a particular method or model is performing in terms of its predictions or outcomes. Therefore, the statement that "Statistical learning is accurately assessing the performance of a method" is true.

Linear regression is used for variables?
- A.
  
  True
- B.
  
  False
- C.
  
  Maybe
- D.
  
  None of the above
Correct Answer
A. True

Explanation
Linear regression is used for variables because it is a statistical technique that is used to model the relationship between a dependent variable and one or more independent variables. It is commonly used to predict or estimate the value of the dependent variable based on the values of the independent variables. Therefore, linear regression is a suitable method for analyzing and understanding the relationship between variables.

Which is not a type of linear regression?
- A.
  
  Simple linear regression
- B.
  
  Bi-linear regression
- C.
  
  Multiple linear regression
- D.
  
  None of the above
Correct Answer
B. Bi-linear regression

Explanation
Bi-linear regression is not a type of linear regression. Linear regression models the relationship between a dependent variable and one or more independent variables using a linear approach. Simple linear regression involves only one independent variable, while multiple linear regression involves more than one independent variable. However, bi-linear regression does not exist as a recognized type of linear regression.

5.

Which of these uses one independent variable?
- A.
  
  Bi-linear regression
- B.
  
  Multiple linear regression
- C.
  
  Latitude
- D.
  
  None of the above
Correct Answer
D. None of the above

Explanation
The given options are bi-linear regression, multiple linear regression, and latitude. Bi-linear regression and multiple linear regression both involve the use of multiple independent variables. Latitude, on the other hand, is not a statistical model and does not involve the use of any independent variables. Therefore, none of the given options uses only one independent variable.

Rate this question:
6.

Which uses more than one independent variable in the linear regression?
- A.
  
  Simple
- B.
  
  Bi
- C.
  
  Multiple
- D.
  
  None of the above
Correct Answer
C. Multiple

Explanation
Multiple regression uses more than one independent variable in the linear regression model. In this type of regression, the relationship between the dependent variable and multiple independent variables is analyzed simultaneously. It allows for the examination of the individual effects of each independent variable on the dependent variable, while controlling for the effects of other variables. Therefore, the correct answer is "Multiple".

Classification is putting things in their best category.
- A.
  
  True
- B.
  
  False
- C.
  
  Hardly
- D.
  
  Sometimes
Correct Answer
A. True

Explanation
Classification is the process of organizing or categorizing things based on their similarities or characteristics. It involves identifying the best category or group for each item or concept. Therefore, the statement "Classification is putting things in their best category" is true as it accurately describes the purpose and nature of classification.

What's is dichotomous?
- A.
  
  Binary
- B.
  
  Hexadecimal
- C.
  
  Two techniques
- D.
  
  None of the above
Correct Answer
A. Binary

Explanation
Dichotomous refers to something that is divided into two parts or has two distinct alternatives. In this context, binary is the correct answer because it is a system of numbering or representing information using only two digits, 0 and 1. Binary is commonly used in computer science and digital electronics, where data is represented using binary digits or bits. It is a fundamental concept in computing and forms the basis for all digital communication and computation.

Is the discriminant analysis a Technique?
- A.
  
  Yes
- B.
  
  No
- C.
  
  Complicated
- D.
  
  I don't know
Correct Answer
A. Yes

Explanation
Yes, discriminant analysis is a technique used in statistics and machine learning. It is a multivariate statistical method used to determine the differences or similarities between groups based on a set of predictor variables. It helps in classifying observations into different groups or categories based on their characteristics. Therefore, the correct answer is "Yes."

What theorem does discriminant analysis use?
- A.
  
  Boyce's Law
- B.
  
  Pythagoras Theorem
- C.
  
  Bayee Theorem
- D.
  
  All of the above
Correct Answer
C. Bayee Theorem
