Summary of Statistic 2

 

Hi, have a great day today...

 

In this day I want to share of Statistic again but the topics is about how we want to calculate the probability of mean, proportion and variance.

 

What is the mean meaning ? Actually mean is an average.

 

Normally we find the probability of some data like the marks of student. For example the probability of the marks of student getting A in examination.

 

But In this topic, we would like to find the probability of the marks average of student getting score 50% and above. Not the probability of one student getting score 50% and above but the probability of average of marks of the student getting score 50% and above.

 

It is same to proportion and variance. We use Sample Distribution to find the probability of the Mean, Proportion and Variance.

 

Ocay, that`s all for today...

 

Oh yaa.. I have been selling of Magnetic USB Fast Charging Micro / Type C Cable. It is Magnetic Cable normally used to charge your smartphone..
