examples in types of experimental methods
Lab Experiment
Field Experiment
Natural Experiment.
Answer:
Experimental research for individuals in the physical sciences and many other fields is the best-known kind of research design. The main reason is that experimental research is a typical scientific experiment, similar to that carried out in secondary schools.
Explanation:
The types of research designs are determined by how the researchers assign subjects to various conditions and groups. They are of three different types: pre-experimental, almost experimental, and real experimental research.
Pre-experimental Research Design:-
In pre-experimental research, the effect of the application of a supposedly changing independent variable is observed by either a group or different dependent groups. It is the simplest form of experimental design and does not involve a control group.
Quasi-experimental Research Design:-
The term "almost" refers to partial, half, or pseudo. The quasi-experimental research therefore resembles, but not the same, the real experimental research. The participants are not assigned randomly in quasi-examples and are therefore used in environments that are difficult or unable to randomize.
True Experimental Research Design:-
To confirm or refute a hypothesis, real experimental research is based on statistical analyses. It is the most exact experimental type and can be performed on two randomly assigned subjects with, or without a pretest.
The true experimental design of the research must include a control group, a variable that the researcher can manipulate and the distribution must be random.
Write a program that asks the user to enter 5 test scores. The program will display a letter grade for each test score and an average grade for the test scores entered. Three functions are needed for this program.
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
double average(double s1, double s2, double s3, double s4, double s5){
double avg = (s1 + s2 + s3 + s4 + s5)/5;
return avg;}
char lGrade(double score){
char grade;
if(score>= 90 && score <= 100){ grade ='A'; }
else if(score>= 80 && score <= 89){ grade ='B'; }
else if(score>= 70 && score <= 79){ grade ='C'; }
else if(score>= 60 && score <= 69){ grade ='D'; }
else if(score < 60){ grade ='F'; }
return grade;}
int main(){
double s1,s2,s3,s4,s5;
cin>>s1>>s2>>s3>>s4>>s5;
double avg = average(s1,s2,s3,s4,s5);
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
cout<<avg<<" "<<lGrade(avg)<<endl;
return 0;}
Explanation:
The three functions to include in the program are not stated; so, I used the following functions in the program
1. The main function
2. average function
3. Letter grade function
The average function begins here
double average(double s1, double s2, double s3, double s4, double s5){
This calculates the average
double avg = (s1 + s2 + s3 + s4 + s5)/5;
This returns the calculated average
return avg;}
The letter grade function begins here
char lGrade(double score){
This declares the grade
char grade;
If score is between 90 and 100 (inclusive), grade is A
if(score>= 90 && score <= 100){ grade ='A'; }
If score is between 00 and 89 (inclusive), grade is B
else if(score>= 80 && score <= 89){ grade ='B'; }
If score is between 70 and 79 (inclusive), grade is C
else if(score>= 70 && score <= 79){ grade ='C'; }
If score is between 60 and 69 (inclusive), grade is D
else if(score>= 60 && score <= 69){ grade ='D'; }
If score is less than 60, grade is F
else if(score < 60){ grade ='F'; }
This returns the calculated grade
return grade;}
The main begins here
int main(){
This declares the 5 scores
double s1,s2,s3,s4,s5;
This gets input for the 5 scores
cin>>s1>>s2>>s3>>s4>>s5;
This calls the average function for average
double avg = average(s1,s2,s3,s4,s5);
This calls the letter grade function for the 5 scores
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
This calls the average function for the average
cout<<avg<<" "<<lGrade(avg)<<endl;

If there are 18 people in your class and you want to divide the class into programming teams of 3
members, you can compute the number of different teams that can be arranged using this formula
(n!/r!(n−r)!).
Using a combination method to determine how many ways can 18 people be divided into programming teams of 3 members, the number of programming teams can be arranged in 816 ways.
What is Combination?In mathematical model, a combination is a mathematical approach for calculating the number of potential arrangements in a set of things without taking the order arrangement of the items is into consideration.
It can be expressed by using the formula;
[tex]\mathbf{ _nC_r = \dfrac{n !}{ r!(n-r)! } }[/tex]
where:
[tex] \mathbf{ _nC_r = number \: of \: combinations \: \} }[/tex]n = total number of set objects = 18r = number of choosing objects = 3[tex] \mathbf{ _nC_r = \dfrac{18!}{ 3!(18-3)! } }[/tex]
[tex]\mathbf{ _nC_r = \dfrac{18!}{ 3!(15)! } }[/tex]
[tex] \mathbf{ _nC_r = \dfrac{18 \times \: 17 \times \: 16 \times 15!}{ 3!(15)! } }[/tex]
[tex]\mathbf{ _nC_r = \dfrac{18 \times \: 17 \times \: 16 }{ 3 \times \: 2 \times 1} }[/tex]
= 816 ways

In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.

Explain why it is important that software products are developed and delivered quickly. Why is it sometimes sensible to deliver an unfinished product then provide issue new versions of that product after delivery?
Answer:
The reason why software products are developed and delivered quickly is because
most of the time client cannot wait an extended time for the merchandise to be developed and delivered because the delay in delivery of software products might cause a loss for the client if that specific software is being developed for the client's business solution. In some mission-critical applications like defense systems, space research systems in such cases software must be delivered as quickly as possible because the project which is getting into such area cannot await an extended time for a software package to be delivered as here time constraint is involved and delay in at some point might cause a loss for an entire ongoing project.Explanation:
Sometimes sensible to deliver an unfinished product then issue new versions of that product after delivery because
Sometimes the software that has got to be developed could be very big which isn't possible to develop during a shorter time and even client cannot wait an extended time for he's software in such case only the primary main core functionality of the software is being developed and delivered to the client and in later version remaining functionality's are included and delivered.
Even it is often the case that software that has got to be developed is very complex and should get lots of obstacles during development in such cases also only the core functionalities are being developed and delivered and in later version remaining functionality's are included.
3) Presence of bugs in software may also lead to issue a new version of that software after delivery and then fix the bug and deliver the new version to the client.
Speed is very important in software development. This is because Developers are known to be under pressure every time to produce high-quality code as fast as they could so that they can fulfil contracts, acquire new customers, retain existing customers and others.
What is vital in delivery of a software project?The key point that is vital is the provision of the right software delivery tools and equipment at a quick and right way.
Some other important software delivery best practices is that a software developer must ensure that their team has everything they need, ranging from hardware to software/testing applications too others.

Suppose you have some List of S List of Strings called List and a String prefix. Write a method that removes all the Strings from list that begin with prefix. public void removePrefixStrings(List-String- list, String prefix) 7. What is the time complexity of this algorithm?
Answer:
public void removePrefixStrings(List<String> list , String prefix) {
if(list==null || list.size()==0)
return;
for(int i=0; i<list.size();) {
if(list.get(i).startsWith(prefix))
list.remove(i);
else
++i;
}
}
Time Complexity: If the prefix is the same as String length, Then finding all prefix match will take n *n = n2
Then removal is also n
So the total time complexity is O(n3)
Prime numbers can be generated by an algorithm known as the Sieve of Eratosthenes. The algorithm for this procedure is presented here. Write a program called primes.js that implements this algorithm. Have the program find and display all the prime numbers up to n = 150
Answer:
Explanation:
The following code is written in Javascript and is a function called primes that takes in a single parameter as an int variable named n. An array is created and looped through checking which one is prime. If So it, changes the value to true, otherwise it changes it to false. Then it creates another array that loops through the boolArray and grabs the actual numberical value of all the prime numbers. A test case for n=150 is created and the output can be seen in the image below highlighted in red.
function primes(n) {
//Boolean Array to check which numbers from 1 to n are prime
const boolArr = new Array(n + 1);
boolArr.fill(true);
boolArr[0] = boolArr[1] = false;
for (let i = 2; i <= Math.sqrt(n); i++) {
for (let j = 2; i * j <= n; j++) {
boolArr[i * j] = false;
}
}
//New Array for Only the Prime Numbers
const primeNums = new Array();
for (let x = 0; x <= boolArr.length; x++) {
if (boolArr[x] === true) {
primeNums.push(x);
}
}
return primeNums;
}

If i took my SIM card out of my phone and put it in a router then connect the router and my phone with Ethernet cable would the ping change?
Answer:
The ping will change.
Explanation:
Assuming you mean ping from device with SIM card to another host (no mater what host), the ping will change. Ping changes even on the same device because network speed and performance of all the nodes on the route changes continuously. However, if two of your devices (phone & router) are configured differently (use different routing under the hood), then it will also affect the ping.

Assume that the PIC18F is currently executing a 16-bit instruction addressed by 0x00015A. What are the current contents of the program counter
Answer:
0x00015C
Explanation:
Given that the counter is executing a 16-bit instruction ( currently )
addressed as 0x00015A
The counter keeps/records the address of the next executable instruction hence the current contents of the program counter
= 0x00015A + 16 bits note: ( 16 bits = 2 bytes )
hence current content of program counter = 0x00015C
