He
has 15 socks that are black with small stripes and 15 socks that are plain
black. Andrew has to pull out one sock; then the second sock Andrew pulls out
must match the first sock. Andrew having two matching socks is dependent upon
which sock he pulls out first and which sock he pulls out second. In this
case, you have two events to consider. This is an example of conditional
probability, which is probability of a second event happening given that
a first event has already occurred. This particular case of conditional
probability deals with dependent events, which is when one event
influences the outcome of another event in a probability scenario. |

apply binomial distribution and in which situation it can be applicable. |
binomial
distribution model is an important probability model that is used when there
are two possible outcomes (hence "binomial"). In a situation in
which there were more than two distinct outcomes, a multinomial probability
model might be appropriate, but here we focus on the situation in which the
outcome is dichotomous. |

distribution may be useful to model events such as ·
The number of meteorites greater than
1 meter diameter that strike Earth in a year |
https://www.slideshare.net/jillmitchell8778/poisson-lecture |
https://www.slideshare.net/abdulkader28696/poisson-distribution-assign |
Because of this application, Poisson distributions are used
by businessmen to make forecasts about
the number of customers or sales on certain days or seasons of the year. In
business, overstocking will sometimes mean losses if the goods are not sold. |
|
DAY 9 |
Poison distributions |
·

emergency room between 10 and 11 pm ·
The number of laser photons hitting a
detector in a particular time interval |
https://www.slideshare.net/abdulkader28696/poisson-distribution-assign |
A textbook store rents an average of 200 books every
Saturday night. Using this data, you can predict
the probability that more books will sell (perhaps 300
or 400) on the following Saturday nights. Another example is the number of
diners in a certain restaurant every day. If the average number of diners for seven days is 500, you can predict the
probability of a certain day having more customers. |
|
|
DAY 10 |
Normal Distributions |
A normal
distribution is the proper term for a probability bell curve. In a normal
distribution the mean is zero and the standard deviation is 1. It has zero
skew and a kurtosis of 3.Normal distributions are symmetrical, but not all
symmetrical distributions are normal. |

known as the Gaussian distribution and the bell curve. |

Mathematical Expectation |
The mathematical
expectation of an indicator variable can be zero if there is no
occurrence of an event A, and the mathematical expectation of
an indicator variable can be one if there is an occurrence of an event A.
Thus, it is a useful tool to find the probability of event
A. |
The concept
of MGF is an elegant one. The MGF packages all the moments for a random
variable into one simple expression. It provides a unique characterization of
the distribution of a random variable. By finding the first and second
moment, one can easily calculate the mean and the variance, and so on. More
importantly, it can be used to prove the equivalence of two probability
distributions. |

Lesson 3
|
1 |
Factual |
In statistics, quality assurance, and survey methodology, sampling is the selection
of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the
whole population. |
|
2 |
Conceptual |
The primary
goal of sampling is to get a representative sample, or a
small collection of units or cases from a much larger collection or
population, such that the researcher can study the smaller group and produce
accurate generalizations about the larger group. |
|
3 |
Procedural |
It allows us
to get near-accurate results in much lesser time. When you use proper
methods, you are likely to achieve higher level of accuracy by
using sampling than without using sampling in some cases due to reduction in
monotony, data handling issues etc. |
|
4 |
Applied |
A large
number of analyses is carried out, e.g., for process control, product quality
control for consumer safety, and environmental control purposes. The sampling theory developed by Pierre Gy, together with
the theory of stratified sampling, can be used to audit and optimize
analytical measurement protocols. |

Sample size
determination is the act of
choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of
any empirical study in which the goal is to make inferences about a population from a sample. |

2 |
Conceptual |
Sampling is a tool that is used to indicate how
much data to collect and how often it should be collected. This tool defines
the samples to take in order to quantify a system, process, issue, or problem.
... The sample, the slice of bread, is a subset or a part of the

Curve
fitting examines the relationship between one
or more predictors (independent variables) and a response variable (dependent
variable), with the goal of defining a "best fit" model

2 |
Conceptual |
Correlation is a measure of the association between
two variables. This tests the strength of linear association
between two variables. ... Thus data that followed an exponential pattern
would have a Pearson correlation coefficient less than one
(possibly much less), although there is a perfect association. |

Curve fitting is
the process of constructing a curve, or
mathematical function, that has
the best fit to a series of data points, possibly subject to constraints |

Applied |
The most
commonly used techniques for investigating the relationship
between two quantitative variables are correlation and
linear regression. Correlation quantifies the
strength of the linear relationship between a pair of variables,
whereas regression expresses the relationship in the form of
an equation. |

Day - 4 |
Range chart or R-chart |
An industrial process produces a speed
sensor for an ABS electronic control. The sensor specifications require that
the variable X = “impedance” is 30 kohms ±10 kohms. To perform the
statistical control of this process 6 sample sensors are collected every half
hour. With the collected data, a total of 30 samples, the following
information were obtained: ¯x = 30.11 and ˆs¯x = 2.00. a) Construct control charts
to monitor that the population mean and variance remain constant. |
Quality control charts represent a great tool for engineers
to monitor if a process is under statistical control.
They help visualize variation, find and correct problems when they occur,
predict expected ranges of outcomes and analyze patterns of process variation
from special or common causes. |

DAY 7 |
Attributes charts |
The p,
np, c and u control charts are called attribute control charts. These four
control charts are used when you have "count" data. There are two
basic types of attributes data: yes/no type data and counting data. The type
of data you have determines the type of control chart you use. |

To understand
about p-chart |
Control
charts dealing with the number of defects or nonconformities are
called c charts (for count). |

DAY 9 |
Construct p-chart |
To understand about p-chart. |
Examples of quality characteristics that are attributes
are the number of failures in a production run, the proportion of
malfunctioning wafers in a lot, the number of people eating in the cafeteria
on a given day, etc. |

DAY 10 |
Constsruct cp-chart |
We
measure weight, height, position, thickness, etc. If we cannot represent a
particular quality characteristic numerically, or if it is impractical to do
so, we then often resort to using a quality characteristic |
