hello this with a disease and I have just recorded a lecture of a statistics introduction in co2 and Hindi that took 30 minutes but this time I will not take more than 10 minutes to wrap up the walls introduction on the statistics ok fine so we simply go quickly what is statistics according to some people is statistics in a branch of mathematics but it is in a development phase one day his artistic will be a different subject and which will not be treated as a branch of any subject but till late 2017 if statistics is treated as a branch of itself and a branch of mathematics so to understand if statistics we have to understand data but what is data data data in the piece of information or measurement wrong an experiment then as a beautiful mission or measurement which we get which we get from an experiment so now in the statistics what we do with the data we perform in collection of data means the collection of data is a part of the statistics we perform some some sort of some sort of models some sort of mathematical models we say we perform mathematical calculations on that data we discuss those calculations in detail in just few minutes that we perform some mathematical calculations on the data we analyze data and then we present data to the penetration of data analysis of data mathematical calculation those be performing data all are included in statistics so this is here if statistics is a part in a branch of mathematics mainly deal with the collection of data and analysis of data presentation of data results which we get from data and ultimately we infer some basic or advanced knowledge about the data on the bridges in statistics so mainly the statistics deals with all the operations which we perform on that and how we get the data any experiment for example we want to measure the average height of us so what we do we collect the heights of each person living in United States of America that will be our raw data and then we perform calculations on that okay next okay now we terminology to understand the basis or the subject statistics we have to understand some concepts yeah those concepts are very important so first of all we have to understand the difference between population and sample population refers to the whole population for example diverse population approximately is this much and from that population if we are interested in any part of the world for example in any particular PD in any particular school in any particular organization that will be treated as sample so population versus sample population refers to whole and sample is a part of population sample is a part of population now with this we have to understand what is a parameter and that stick statistical parameter is the characteristic parameter is the characteristic of population why is statistics is the characteristics of a sample statistic in the above sample if you want to study population whatever we study in population and we present that data in terms of numerical values those numerical values will be treated as parameter on the other hand when we study a sample so whatever we study during the example so all the characteristics will be treated all its statistics for example the mean of a population will be called parameter its standard deviation of a popular population will be called parameter saying mean median mod whatever we will find regarding population that parameter will be treated as population characteristics here so all the parameters of a population are called parameter either it is mean median mode and in sample they call consistent characteristics for example the mean median standard deviation our samples are called it statistic so the same characteristic of a population is known as parameter the same characteristic of a sample is known as a statistic to memorize this concept P P for population and people parameter on the other hand s for sample s for statistical now come to the next point these are the two main terminology those are important now come to the branches of a statistics it statistics can be divided into two broad categories one is known as this clip tip statistics another one is known as influential in descriptive statistics we study the graph related to the data for example we are making bar chart we are making pie chart all the graphical presentation comes under the head of descriptive statistics apart from that we study mean median mode standard deviation variance kurtosis skewness range maximum minimum the total number of observations and definitely the total number of observations and in descriptive statistics so now what inferential statistics deals with in central statistics deals with the hypothesis testing Peters and Nova I know why I've invented by the father of his statistics which is known as Ronald Fisher so ANOVA and analysis of variance is invented by me father of statistics then we have Peter chi-square then we have regression regression check the dependency of one variable over the other co-relation correlations check the relationship between two variables for example between electricity and your any other expense you can say the talocan expanse and the electric expense you can find out the correlation between them so these things comes under the hands of inferential statistics while in descriptive statistics we include the graph mean median mode variance ketosis and a lot more things next I just want to quickly wrap up the induction we have in the statistics tutoring we help in assignment making and for all the levels for MBA level a level GTAC level next we are moving yeah here I just want to give you a small introduction about we does studied we have self sister did that the difference between parameter parameter are the characteristics of whom population while is statistic refers to the characteristics of sample so now I just want to give you the male's the simple which we used to refer them for example the number of observations if we refer it to the population we used and capital and why example statistic it's referred to small sense then when we call about the mean the average so when we refer to the average of a population we use mu it will be like this and for a sample statistic the symbol will be X bar then we have its standard deviation the standard deviation we use Sigma and for sample s is used small n it will be a small s for sample statistics while for population parameter we use Sigma for a segregation variants for variance it is Sigma square and for sample statistics will be s square so these are the main symbols which are used in statistics and the difference between population parameter and sample statistics as we have told you before that parameter parameter refers to the characteristics of population while in statistic refer to the characteristics of sample now we are moving to our last part and what are the difference DICE off a bridges there are three main types of averages me median and modest more is most repeated were you in a data center median is the middle both values for double if one two and three written to in median while meat is simple average yes a bottle that we have mean is also called arithmetic mean and we have two more means harmonic mean and geometric mean harmonic mean and geo-buk signal so statistics is all about comparison it's all about interpretation it's all about presenting a data and when you become or you will get familiar with the statistics you will start thinking like a statistician and you will always find the differences your whole thinking will be changed that's all about exaction I hope you liked the video you can watch the same video again and again to get better diesel and we will keep on recording more videos and some ability because the statistics without probability is nothing from my point of view so permeability is the most from the polity is the most important topic of the statistics you can connect us on plus nine to three hundred nine to three hundred to five six double two nine six on whatsapp we offer one to one online tutoring of the statistics assignments house and a lot more you can connect me on the number thank you for watching my video take care
