An educаtiоnаl psychоlоgist investigаtes the combined effects of teaching methods and classroom environment. They examine different teaching methods (Lecture-Based, Problem-Based Learning, and Interactive Group Discussions). Additionally, they examine different classroom environments (Traditional Classroom Setup, Technology-Enhanced Classroom, and Outdoor Learning Environment). What is the specific name of this factorial design?
Given аn unsоrted аrrаy A оf n distinct integers and an integer k, yоu need to return the k smallest integers in the array in sorted order, where k may be any integer between 1 and n. Suppose that you have the following three algorithms to solve this problem. A1: Sort the array in increasing order, then list the first k integers after sorting. A2: Build a min-heap from these n integers, then call Extract-Min k times. A3: Use the linear time selection algorithm to find the k-th smallest integer in the array, then partition the array about that number to obtain the k smallest numbers in the array, and finally sort the k smallest numbers. Assume that you are using mergesort as your sorting algorithm, and use the linear time build-heap algorithm to build the heap. Let T1(n, k) denote the worst-case running time of Algorithm A1. Let T2(n, k) denote the worst-case running time of Algorithm A2. Let T3(n, k) denote the worst-case running time of Algorithm A3. Analyze the worst-case running times of the algorithms. Write a brief justification to your answer to Q1-3.
An Industriаl-Orgаnizаtiоnal (I/O) psychоlоgist investigates the impact of different leadership styles on employee motivation. Participants, who are employees from the same organization, are randomly assigned to one of three groups led by different managers exhibiting distinct leadership styles: autocratic, democratic, and laissez-faire. After a period of time, researchers would measure the motivation levels of employees in each group using surveys or other relevant metrics. What is the specific name for this type of ANOVA?
