Question Description

Scenario:

A large number of patients having Pneumonia like symptoms were reported in Wuhan, a capital city of China’s Hubei province in mid-December 2019. This Pneumonia like disease was declared an outbreak of a new virus and was reported to the World Health Organization (WHO) country office in China on 31 December 2019 and later it was officially named as COVID-19 by the WHO due to its novelty. The outbreak was declared a Public Health Emergency of international concern on 30 January 2020 (WHO) and declared as Pandemic and various precautionary measures were recommended by the WHO to all the countries of the world to slow the spread of the virus by keeping social distancing, washing hands, wearing masks, testing and treating patients, carrying out contact tracing, limiting travels, quarantining citizens, and canceling large gatherings such as weddings, sporting events, concerts, and closing of schools and universities. At one time, many of the countries placed complete lockdown in their most effected cities to halt the spread of this virus.

Since its emergence in Wuhan, China late last year, the virus has spread to almost every corner of the world. Cases are rising exponentially with an increased number of casualties. This coronavirus (COVID-19) pandemic has become the most crucial global health crisis of the last 100 years. It has posed the greatest challenge we have faced since world war two (WW-II). But COVID-19 is much more than a health crisis. By stressing every one of the countries it touches, it has the potential to create devastating social, economic, and political crises that will leave deep scars (UNDP).

For instance, social impacts may include an increase in crime rate, domestic violence, frustration, anxiety, depression, quarantine fatigue, and increased unemployment due to the outbreak of COVID-19.

Talking about political impacts, important national and international projects may have been either completely shut down or delayed, significant political figures are catching the virus, and some have died; besides, budget management failure is also another biggest issue. While, concerning the impact of this pandemic on economics, stock markets are crashed, many businesses have been shut down, supply shortages in the markets is a big issue due to delayed shipments, and so on.

Requirements:

You are advised to thoroughly read the above scenario about COVID-19.

Dependent Variable COVID - 19
Independent Variable Crime rate, Anxiety , depression , Farutation, Qurantine Fatigue etc
Sec solution
Ho there is no significant relationship between crime rate and covid - 19
H1 there is significant relationship between crime rate and covid-19
same baki variables ka bi asa hi hypothesis likhein gy...

After reading the scenario ,
Variable:
A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure.
There are two types of variables.
1) independent-variable
2) dependent-variable
Independent - variable:
An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.
Dependent-variable:
Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
Hypotheses of variables-independent and dependent:
coronavirus (COVID-19) is an independent variables. According to given definition we can identify the independent variables. Coronavirus(COVID-19) is change the whole world.
(Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).some dependent variables are those which are changing by coronavirus (COVID-19) .
keeping social distancing, washing hands, wearing masks,  testing and treating patients, carrying
out contact tracing, limiting travels, quarantining citizens, and canceling large gatherings such
as weddings, sporting events, concerts, and closing of schools and universities

In the given scenario, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
Variables are given a special name that only applies to experimental investigation one is called the dependent variable and the other the independent variable.
The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.Example of independent variables is coronavirus (COVID-19) in given scenario.
The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. An example of a dependent variable is depression, crime rate,Anxiety,depression,farutation, quarantine Fatigue which depends on the independent variable.
Hypotheses: In an experiment on the effects coronavirus (COVID-19), for example, researchers might look at several different types of virus. coronavirus (COVID-19) that the experimenters look at would be a different level of the independent variable while depression, crime rate,Anxiety,depression,farutation, quarantine would always be the dependent

STA630 GDB Solution idea:

 

After reading the scenario,

Variable:

A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure.

There are two types of variables.

1) independent-variable

2) dependent-variable

 

Independent - variable:

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.

 

Dependent-variable:

Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.

 

Hypotheses of variables-independent and dependent:

  • coronavirus (COVID-19) is an independent variables. According to given definition we can identify the independent variables. Coronavirus(COVID-19) is change  the whole world.
  • (Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).some dependent variables are those which are changing by coronavirus (COVID-19).
  • keeping social distancing, washing hands, wearing masks, testing and treating patients, carrying out contact tracing, limiting travels, quarantining citizens, and canceling large gatherings such as weddings, sporting events, concerts, and closing of schools and universities.
