Collect and represent data

Before doing an experiment or for making some decision that are based on some previous data there will be of collect and represent the data .This is the only way through which one can easily, efficiently makes the effective plan or strategies that are totally base on the previously stored data .Before storing the data it should be keep in mind that how data is collected and also from where data is collected.

Data should be collected correctly as well as from the true resource that have the timeliness that means when data is needed by someone it can be easily retrieved by them and after collection of the data it should be organized according to some keys .
After all the collection and organization of the data there will be next very important concept of representing the data. It is the only concept through which the user can understand the previously recorded data and makes some decision on that .Collect and represent data in probability are also helpful that means there data are used to making the future strategies as well as helps in comparison of the data among several years for the same period of time .
There are several Data Collection Methods and various type of data representation like image processing, Global positioning system .The main motive behind display the data is to understand the available data and deriving the meaning and also extract the useful in conclusion .The representation of data can be done in many ways like:
Statistical tables
or by rank order
or by frequency order .
These forms are useful in statistical analysis of the data .Initially all the data collect in scattered form but later it organize and change into the numerical facts .

Probability and Statistics

In this unit we will learn about Probability in Statistics.  The study of probability was introduced for the study of games and cards.
It includes the study which requires the possibility of certainty and chance. How to Solve Probability Problems ? We say that probability is the concept of study of numerical measures of possibility of any event to occur.  So we say that uncertainty is the measure of not occurrence of the event and the certainty is the possibility of occurrence of the event numerically. More details on this subject.
When we need to find the probability of occurrence of any event, we need to look carefully at the experiment.  We say that an experiment is the operation which can produce well defined outcomes of the collection of the events.  In each trial of an experiment, we observe if it is conducted under same and under ideal conditions, then we observe that the outcomes are not the unique solutions, then  if we pick any one of the random event and take its observation  , then we call it the random experiment conducted to measure the possibility of the occurrence of the  event. We come across so many events in our day to day life, which help us to measure the probability of the event. Example: rolling a dice, tossing a coin, pulling out a card out of the pack of 52 cards. We call all of them as the set of random experiments. They help us to find the numerical value of the probability of the random experiment. You can also play probability worksheets grade 3.
 We must also know the term sample space used in the study of probability. We say that a sample space is the set of all possible outcomes in the random experiment which is represented by the variable “S”
