Please discuss your feelings about data transformation. Was this the first time that you had heard of it? What do you think? Does this affect your feeling about the statistics that you hear every day? One thing that I'm hoping to read from you is if you are now seeing statistics in a different light. These last couple of chapters bring it all together. You've learned so much these past 13 weeks---now it's time to be able to talk about it.

Which of the following statement(s) is/are correct for boosting technique? A) Weight of observation, to be selected while building the next weak learner, increases if the observation is correctly classified B) Weight of observation, to be selected while building the next weak learner, increases, if the observation is incorrectly classified C) Weight of observation, to be selected while building the next weak learner,  decreases if the observation is correctly classified D) Weight of observation, to be selected while building the next weak learner,  decreases if the observation is incorrectly classified

Draw the ER/EER model for the given scenario. Manufacturer have unique name, an address, and a phone number. Products have a product_id, a name and price. Products may be classified into electronics and grocery. Electronic products have description, type attributes. Groceries have fssai_number, date_of manufacture, date_of_expiry. Each product is made by one manufacturer, and different manufacturers may produce different products.. Customers are identified by their unique social security number. They have email addresses, and physical addresses. Several customers may live at the same (physical) address, but we assume that no two customers have the same email address. An order has a unique order number, and a date. An order is placed by one customer. For each order, there are one or more products ordered, and there is a quantity for each product on the order

QUESTION 3 Which of the following items were described as problems with the EJI (Racial Terror Lynching) visualizatio n? (Select all that apply) The visualization doesn't provide accurate information about the number of lynchings in the deep south. It suggests that racist violence was a problem restricted to the deep south. The EJI dataset was very small. The use of aggregated death counts dehumanizes the data. The visualization is intended to be persuasive. O The data was not collected using principled techniques.

The authors of a paper on perceptions of video games carried out an experiment to determine if restrictive labels on video games actually increased the attractiveness of the game for young game players. Participants read a description of a new video game and were asked how much they wanted to play the game. The description also included an age rating. Some participants read the description with an age-restrictive label of 7+, indicating that the game was not appropriate for children under the age of 7. Others read the same description, but with an age-restrictive label of 12+, 16+, or 18+. The following data for 12- to 13-year-old boys are consistent with summary statistics given in the paper. (The sample sizes in the actual experiment were larger.) For purposes of this exercise, you can assume that the boys were assigned at random to one of the four age label treatments (7+, 12+, 16+, and 18+). Data shown are the boys' ratings of how much they wanted to play the game on a scale of 1…

A derived attribute can be stored in a table or calculated on each occasion that it is required. An example of a derived attribute is your Grade Point Average which is calculated by adding together a score for each unit (e.g., HD=4, D=3, C=2, P=1, N=0) and dividing that by the number of units you have completed. Explain how the decision as to whether the Grade Point Average would be stored in a table or calculated would be made.    You are administering a database in a large retail company that records sales at each of the company’s stores. Tuning the database to improve performance by adding indexes and optimising query execution is an important ongoing aspect of the physical database design.   Which attributes in a database such as this (apart from the primary key) are likely to BENEFIT from being indexed?  Which attributes would you generally avoid indexing, and why?

. Consider the following scenario and answer the questions given atthe end The study involved 55 students (23 male, 32 female) and used a mixed methods approach,involving a questionnaire with open ended questions, Likert scale questionnaire and interviewsthat aimed to determine students' perceptions of their performance. Five main areas wereinvestigated with the open-ended questions: defining clinical reasoning; advantages anddisadvantages of clinical case studies; the effectiveness of clinical case studies in comparisonto real patients; and whether clinical case studies helped students working in a sports injuryclinic. Students completed a 5-point Likert scale that asked three statements regarding theclinical environment. Following the questionnaire, a sample of 15 students were randomlyselected for individual interviews. The results suggested that the students' responses weregenerally in favour of the use of clinical case studies to aid the development of confidence,communication and…

Please describe the relationship between bias, variance, underfitting, and overfitting. Support your answers with examples if needed.

need diagram only Draw an ER diagram for the following scenario: A designer has a store of designer dresses both for male and female. People can buy as well as take dresses on rent from the store. Each dress in the designer's store, is identified by unique ID. A dress in the store can be categorized into various categories Western, Indian, Indo-westem, etc. The designer maintains the name, phone number of people who have taken dresses on rent. The designer also maintains the name, phone number, and address of people who have bought dresses from the store. The designer also collects feedback from the people who have bought or taken dresses on rent from the store. Design the ER diagram by mentioning all the structural constraints. You may also include additional information in addition to the requirements listed.

The mayor of a city is interested in learning what goals are most important for residents of the city. Members of her staff visit one of the many neighborhoods in the city and ask 20 residents to fill out a survey. The mayor is concerned that the survey may be biased and not accurately reflect the overall interests in her town. Which of the following strategies is MOST likely to address concerns about the data being biased or inaccurate. A Finding the same people surveyed previously to ask more detailed questions. B) Visiting the same neighborhood to collect more survey responses Visiting multiple new neighborhoods to collect more survey responses D Having her staff collect the data using an app rather than paper surveys

convert this plain text to ER diagram , I attached a picture with question for one diagram and it's wrong because there is no bookning  "Each office employs one or more dentists, hygienists, andreceptionists each of whom have an employee number. Patientsare free to use any dental office but, naturally, must makeappointments in advance. A record of all such appointments iskept which specifies the patient’s name, the date and time ofthe appointment and a list of services performed. Adultpatients have a SIN (Social Insurance Number) but theirchildren typically do not. Each office provides specific services(e.g. cleaning, filling, X-rays, extraction, etc.) to the patients andbills them accordingly.
