Tutorial 2- What is Population And Sample And Sampling Techniques In Hindi? 

Additional types of sampling Cluster Sampling: Cluster sampling is like picking groups or clusters of individuals from a larger population instead of selecting individuals one by one. Imagine you have a big box of candies, and instead of picking candies individually, you divide the candies into small bags (clusters) first. Then, you randomly choose a few bags, and all the candies in the selected bags become your sample. It's an efficient way to sample when it's hard or expensive to reach individuals directly. 2.Judgmental Sampling (Purposive Sampling): Judgmental sampling is when you choose specific individuals or groups deliberately based on your judgment or knowledge of the population. For example, if you want to study the opinions of experts in a field, you might handpick experts you know and include them in your sample. This method can be useful when you need specialized insights, but it may introduce bias if your judgment is subjective. 3. Snowball Sampling: Snowball sampling is a method used when it's challenging to identify or reach individuals directly. It's like starting with a small snowball and rolling it downhill, and as it rolls, it picks up more snow and becomes bigger. Similarly, you begin by finding a few initial participants (who are part of the target group), and then you ask them to refer others who fit the criteria. This process continues, and your sample grows like a snowball. It's often used in studies involving hard-to-reach or hidden populations.

Exit pole- random sampling Disease information- convenience sampling Household expenses- stratified sampling

1. Exit Poll: Simple random sampling 2. Disease Information: Startified sampling 3. House hold expenses: convenience sampling or voluntary response sampling

1.Exit poll: simple random sampling. 2.Disease information: convenience sampling. 3. house hold expanses: stratified sampling.

Exit poll- simple random sampling. Disease information- convenience sampling. household expenses-stratified sampling.

1) Exit Poll - Random Sampling 2) Disease Information - Voluntary Response Sampling 3) Household expenditures - Stratified Sampling if Women or Voluntary Response Sampling if the situation requires the conclusion from only married people.... please correct me if am wrong and your valuable feedback would strengthen my knowledge, thanks for the wonderful video.

sir aap best ho par apki writing 🤦‍♂🤦‍♂ but you are best 👍👍💕💕

thank u for help , this is great class for aspirent of iitm data science students

Sir, please tell secret of your energy and dedication 😇 thanks for everything.. 😇

Following Your Stats Playlist ,Really Loved it .i Hope you upload all videos soon so that I can learn from them.❤

Generally we use simple random sampling when we have homogeneous type of data. When we have heterogeneous type of data then we divide these data into varipus statras and then select observations from strats randomly ..then this procedure is called stratified random sampling.

Thank you so much for the free provided valuable content..best than the paid version.

Great Explanation Sir. I am already a student of I neuron FSDA 2.0.

Sir ap no doubt bahut achha padhate hai aur bahut achhe se samajh me bhi ata hai lekin thoda Chhota likhte hai ap to dubara dekhne me ham padh nhi pate hai isliye please thoda bade Akshar me likhiye 🙏🙏

In stratified random sampling our objective is to make strats homogeneous as much possible then we simply use simple random sampling.

best guy on youtube. Cheers

Sir chebysev technique and qq plot ka video bhi daldo please 🙏

Sir i this is really helpful and I am binge-watching your tutorial.. Sir i want to be a data analyst and along with this stats series . What are others skills to learn which I can learn free of cost?

wonderfully explained bhai

Can you further explain in more detail the words" Equal Chance" in the random sampling and "Non-Overlapping" in the stratified sampling.

Thank you sir for providing the courses..... sir I have a question that Kya EXIT POLL Stratified sampling ki example ho sakta hai...kye ki 18 sala ki Jada loka ki ak sample and nicha balo ki ak .....and 18 sala ki Jada loka ki ham surva karanga...and nicha balo ko ignore.....

thank you sir for your effort

Sir video puri daal do ztest, ytest wali

Sir Stratified Random Sampling is same as stratified sampling or diffrent

Thank you sir for a such a amazing video can you please make video on how should fresher should switch company in hindi.

Thank you so much sir ❤

Thank u sir

Outstanding

Is the population in the example everyone whose age is > 18 or everyone who actually voted?

sir i am having a doubt "if we have to collect a data that how much students want to take admission in medical collages "which sample techniques will help me ?

Hi Sir, Nicely described video.. I have one doubt Top P and Top K sampling is under which category. plz explain.

Then what is oversamling and undersampling

Ashish chanchlani ka Bhai??

Hi, You have not mentioned about cluster sampling, snowfall sampling, purposive sampling, quota sampling.

great
