- I want to explore the ...
- For that I will use Chi-squared GOF/Chi squared for Independence/t-test (choose appropriate one)

- My hypotheses:
H0: 
H1:  

- What data is required for the test?
- How you will collect the data?
(add sources where you could potentially get the data or useful info, etc.)

For instance, I can choose one zodiac sign as sagittarius and find their characterists written in the zodiac sign. Then I will create the survey where the sagittariuses will answer to what extent each characteristics are about them. For that I will use chi-squared test for goodness. 
My hypothesis: 
H0: sagittarious's behavior follow the zodiac sign characteristics
H1: sagittarious's behavior do not follow the zodiac sign characteristics. 
- Zodiac sign of every surveyer must be sagittarius. Every surveyer will answer from zero to five how much each characteristics given by zodiac sign is relevent to them. 
-I will collect the data by survey and the chacrteristics of sagittarius can be found in the internet (there are a lot of websites about zodiac sign)]]> 2021-04-29 03:38:26 UTC https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472022267 https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472022909 I want to explore the conncetion between the time of day and the reach of people on the social network Instagram.  For that I will use Chi-squared GOF. 

My hypotheses:
H0: The reach of people in the social network depends on the time of day.
H1:  The reach of people in the social network  does not depend on the time of day.

It is needed to find out from people (with the help of a survey) at what time they often use Instagram, in order to compare the results and determine the time when everyone uses the social network to find out whether the reach of people in the social network depends on the time of day. Statistical expected data can be found in secondary sources on the internet.

The secondary source with statistical data: https://popsters.ru/blog/post/luchshee-vremya-dlya-publikacii-v-instagram ]]> 2021-04-29 03:38:44 UTC https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472022909 arashapov_a https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472027923 I want to explore the connection between reaction time and whether the person plays video games. 
For that I will use T test.

H0: People that play video games do not have faster reaction time.

H1: People that play video games have faster reaction time.

Reaction times from different groups of people that either play video games or don't. Also you have to make sure there are no people that are in sports, because that can affect the results.

I will use secondary source data from here.

So, I'll explore are they independent from each other, thus I'll use for that Chi-squared test for independence. 

H0: Genre preferences are independent from gender.
H1: Genre preferences are dependent from gender.

I'll need the data about what genres do different genders like and prefer to read/watch. I can collect the data from the survey among the audience which are interested in manga/anime. Potentially I'll use websites where I can make survey, maybe some anime/manga forums. ]]> 2021-04-29 03:44:31 UTC https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472033534 https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472036222 I want to explore how wake-up time varies from the days in a week. 
For that I will use Chi-squared of Independence
My hypotheses:
H0: There is a relationship between week days and wake-up time.
H1: There is no relationship between days and wake-up time.
For the investigation I need a data about the average time of waking up of people during the days in one week. To collect the data I will find specific amount of participants and ask them to observe the time when they wake up.  ]]> 2021-04-29 03:46:05 UTC https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472036222 https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472049403 I want to explore the connection between the active work hours in a day and season of the year. For this i will use Chi - squared GOF test. 

- My hypotheses:
H0: There is no correlation between the active work hours and seasons of the year.
H1:  There is a correlation between the active work hours and seasons of the year.

- I need to collect the active work hours of students based on the four seasons. 
- I will conduct a survey where people will choose the range of hours between 1 to 5 etc. four times (winter, summer, fall, spring)

My hypothesis:
H0: Older people have slower reaction in terms of driving
H1: Older people do not have slower reaction in terms of driving

The experiment will be provided using online simulations where person should press certain button while the simulation of driving to stop the vehicle. The time data will be collected from 2 different aged groups.

For this I will use Chi-Squared GoF
My hypotheses:
H0: there is no correlation between a person's age and his social media activity

For that I will use Chi-squared test for independence. 

My hypotheses: 
-Ho: There is relationship between gender and number of close friends person has.
-Hi: There is no relationship between gender and number of close friends person has. 

-I need to collect data about number of close friends students have. 
-I will conduct a survey among 40 students. (20 girls, 20 boys). To conduct a survey I will use Google Forms. ]]> 2021-04-29 08:06:27 UTC https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1472672333 https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1475204298 I want to explore the relationship between student's school grades and amount of hours they sleep on average (from monday to friday)

My hypothesis:
-Ho: There is relationship between student's school grades and amount of hours they sleep on average
-Hi: There is no relationship between student's school grades and amount of hours they sleep on average

I will collect information on how many hours 30 students sleep
I will ask for their grades for 5 subjects
I will use Chi-squared test for that.]]> 2021-04-29 18:04:49 UTC https://padlet.com/jamilyaabilzhanova/21r5yjcjo4298lx9/wish/1475204298
