Normal Distribution - Explained Simply (part 1)
*** Check-out the improved version of this video here: https://youtu.be/tDLcBrLzBos I describe the standard normal distribution and its properties with respect to the percentage of observations within each standard deviation. I also make reference to two key statistical demarcation points (i.e., 1.96 and 2.58) and their relationship to the normal distribution. Finally, I mention two tests that can be used to test normal distributions for statistical significance. normal distribution, normal probability distribution, standard normal distribution, normal distribution curve, bell shaped curve

StatQuest: Quantile-Quantile Plots (QQ plots), Clearly Explained
Quantile-Quantile (QQ) plots are used to determine if data can be approximated by a statistical distribution. For example, you might collect some data and wonder if it is normally distributed. A QQ plot will help you answer that question. You can also use QQ plots to compare to different datasets that you collected to determine if their distributions are comparable. This video shows you how to do both things.

Excel Magic Trick #243: MEAN MEDIAN MODE STDEV Histogram
See how to calculate and interpret Mean Median Mode Standard Deviation in Excel. Create a Frequency Distribution and then a Histogram. Basic Statistics. Mean Median Mode, and Standard Deviation Mean Median and Mode are all Averages The reason we have averages is because we need "ONE" value that will represent all the values so we can talk about the "typical score". All the data is so spread out that is hard to talk about 'all" the data unless we calculate a typical value. Here are three ways to calculate a typical value: Mean, Median Mode. MEAN is the arithmetic mean (add all the scores and divide by the count). In Excel we use the AVERAGE function MEDIAN is the one in the middle (position) after we have sorted (this is good when we have extreme values like in real estate (most of the houses are around $200,000, but a few are $1,000,000)). In Excel we use the MEDIAN function MODE is the one that occurs most often. This is good when we have "word" categories such as preference for "cola". In Excel we use the MODE function (It will not tell you when there are more than 1 mode). The Standard Deviation tells you: 1) how spread out the data is; 2) what the mean deviation is; 3) does the average represent its data points fairly. In Excel we use the STDEV function for a sample and the STDEVP function for a population (population is all possible values; sample is some of the values but not all). Histogram. SUMPRODUCT COUNTIF function formula. Column Chart Ampersand Concatenate all these functions ignore blanks or dashes. If you really want to include them you must put a zero instead of a dash or blank.

The Normal Distribution
You have surely seen a normal distribution before as it is the most common one. The statistical term for it is Gaussian distribution, but many people call it the Bell Curve as it is shaped like a bell. It is symmetrical and its mean, median and mode are equal. If you remember the lesson about skewness, you would recognize it has no skew! It is perfectly centered around its mean. Alright. So, it is denoted in this way. N stands for normal, the tilde sign denotes it is a distribution and in brackets we have the mean and the variance of the distribution. On the plane, you can notice that the highest point is located at the mean, because it coincides with the mode. The spread of the graph is determined by the standard deviation. Now, let’s try to understand the normal distribution a little bit better.

I also show calculation of the statistic RMSE (Root Mean Square Error) and use it to represent the quality of fit. The random process model assumes the data fluctuates randomly around a constant level - which we estimate with the mean of the data we've collected.

Import Data, Analyze, Export and Plot in Python
A common task in data science is to analyze data from an external source that may be in a text or comma separated value (CSV) format. By importing the data into Python, data analysis such as statistics, trending, or calculations can be made to synthesize the information into relevant and actionable information. This demonstrates how to import data, perform a basic analysis such as average values, trend the results, save the figure, and export the results to another text file.

Starting with a simple “Hello Word” example, throughout the course you will be able to see how TensorFlow can be used in curve fitting, regression, classification and minimization of error functions. This concept is then explored in the Deep Learning world. You will evaluate the common, and not so common, deep neural networks and see how these can be exploited in the real world with complex raw data using TensorFlow. In addition, you will learn how to apply TensorFlow for backpropagation to tune the weights and biases while the Neural Networks are being trained. Finally, the course covers different types of Deep Architectures, such as Convolutional Networks, Recurrent Networks and Autoencoders. Delve into neural networks, implement Deep Learning algorithms, and explore layers of data abstraction with the help of this Deep Learning with TensorFlow course. - - - - - - - - - - - - - - Who should go for this course?

TensorFlow is one of the best libraries to implement Deep Learning. TensorFlow is a software library for numerical computation of mathematical expressions, using data flow graphs. Nodes in the graph represent mathematical operations, while the edges represent the multidimensional data arrays (tensors) that flow between them. It was created by Google and tailored for Machine Learning. In fact, it is being widely used to develop solutions with Deep Learning. Machine learning is one of the fastest-growing and most exciting fields out there, and Deep Learning represents its true bleeding edge. Deep learning is primarily a study of multi-layered neural networks, spanning over a vast range of model architectures. Traditional neural networks relied on shallow nets, composed of one input, one hidden layer and one output layer. Deep-learning networks are distinguished from these ordinary neural networks having more hidden layers, or so-called more depth. These kinds of nets are capable of discovering hidden structures within unlabeled and unstructured data (i.e. images, sound, and text), which constitutes the vast majority of data in the world. --------------------------------- Instagram: https://www.instagram.com/edureka_learning/ Facebook: https://www.facebook.com/edurekaIN/ Twitter: https://twitter.com/edurekain LinkedIn: https://www.linkedin.com/company/edureka #Autoencoder #Tensorflow #DeepLearning #NeuralNetworks #python #MachineLearning #DimensionalityReduction ------------------------------------- Got a question on the topic?

10. Exercises on Normal Distribution
The lecture spends more time reinforcing the properties of a normal distribution discussed in previous lectures. We talk area under the curve within 1/2/3 standard deviations from the mean as per the normal/z table. Post this lecture the student should be able to grasp the concept of normally distributed variables, how mean and standard deviations can be used to create 90/95/99% confidence intervals around the mean. This playlist provides approximately 10 hours of our Analytics Training series. For more information, please visit www.learnanalytics.in . For enquiries drop an email to [email protected] . The training covers basic business statistics concepts and using tools such as SAS, SPSS , Statistica and R using Rattle. The objective of the training series is to prepare the student for a career in Data Analysis and the Analytics Industry in general. Please visit our website for further details. If you wish to subscribe to our full Analytics Training module, please visit http://goo.gl/nIJJHg for our paid Youtube Channel which contains additional hours covering more extensive topics including Linear Regression/Logistic Regression, building and testing predictive models using Logistic / Decision Trees and Ensembling. All videos on our paid channel are available without advertisement interruptions and you can enrol for a 14 day free subscription trial. You pay only if you want to continue.
