This video is about an Introduction to Statistics. "On Your Own" ANSWERS 1a) Yes, it is a statistical question because you would expect the ages of people who retire early to vary. b) Cluster around 60. Peak at 60 and two gaps, one between 56 and 58 and the other between 62 and 64. c) Most people who retire early are about 60 years old. 2a) 20 students ran the race (there are 20 data points) b) You can collect these data with a stopwatch. The units would be seconds. c) Question: "How long does it take a sixth grade student to run 100 meters?" Answer: It takes most sixth graders about 13.8 seconds to run 100 meters.

9 Awesome Science Tricks Using Static Electricity!
 
05:39
Add me on Facebook. (click the LIKE button on Facebook to add me) http://www.facebook.com/brusspup Music in the video are songs I created. Song #1: Over Rain iTunes: https://itunes.apple.com/us/album/over-rain-single/id1033695238 Amazon: http://www.amazon.com/Over-Rain-brusspup/dp/B014JXPNSW/ Song #2 Soul Switch Remix - Will be available soon All of these tricks take advantage of static electricity. In general, the lower the humidity, the better these tricks will work. The most impressive one to me is the floating bag trick. Depending on the conditions, you can float an entire grocery sack. 1. Hover Plate: (You need Styrofoam Plates and a cloth) Styrofoam plates are great for static electricity tricks. When you give them a charge and hold one above the other, you can feel an incredible amount of resistance. 2. Can Can Go (You need a coke can, PVC pipe and a cloth) This is a classic but still fun. Try standing the can up and then tip it over with static, or try pulling 2 cans at the same time. 3. Stick Around (You need a small wooden stick, glass jar, thread, tape, PVC pipe and a cloth) This one is fun because half of the time the wooden stick will come toward the pvc pipe, and other times it will move away from the pipe. When it moves away, it will stick the the side of the jar and remain there for a period of time. It also fun to use as large a jar as possible to increase the dramatic effect of the pipe moving the stick from such a large distance. 4. Bubble Trouble (You need bubble solution, plexi-glass, PVC pipe, straw and a cloth. This is a fun trick because the bubbles change their shape and move when the pvc pipe is near. It's also fun to create bubbles inside of bubbles to watch the effect of the static electricity. And also create multiple bubbles on the sheet and watch them all travel toward the pipe. 5. Dancing Balls (You need styrofoam balls, aluminum foil, plexi-glass, cloth, and an area to keep the balls from escaping. This trick is really impressive but can be a bit difficult to recreate. When the plexi-glass plate is charged and placed over the balls, they all jump up and stick to the bottom of the glass. For a few moments they travel around sporadically until they finally settle. But when you put your finger near the glass, they all start jumping around. It's also fun to use these balls with styrofoam plates / cups. If you place the ball on a charged plate, it will shoot off of the plate, or stick to it, even if the plate is held sideways or upside down. 6. Water Bender (You need a cup that you can poke a hole in, water, PVC pipe and a cloth. This is a classic but still fun. 7. Balloon Fight (You need balloons, thread, PVC pipe and cloth. When the conditions are just right, the balloon can almost levitate about the pipe. But most of the time you can have fun pushing the balloons around with the charged pipe. 8. Electroscope (You need, steel wire, jar, straw, aluminum foil, PVC pipe and a cloth) This one is really impressive to see in person. A really cool effect to try, which you can see in this video, is to rub the cloth on the pvc pipe from several feet away from the jar. When you run the pipe, you can see the aluminum foil pieces in the jar, moving. I was able to stand as far as 5 feet away and still see the effect. 9. Wingardium Leviosa (You need very light weight / thin plastic bags, cloth, PVC pipe) This is my favorite trick. Again, with the correct conditions, you can get the plastic pieces to float over foot above the pipe. Produce bags from the grocery store work great. You can float an entire produce bag in the right conditions. Have fun!

What is BIOSTATISTICS? What does BIOSTATISTICS mean? BIOSTATISTICS meaning, definition & explanation
 
05:59
What is BIOSTATISTICS? What does BIOSTATISTICS mean? BIOSTATISTICS meaning - BIOSTATISTICS pronunciation - BIOSTATISTICS definition - BIOSTATISTICS explanation - How to pronounce BIOSTATISTICS? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Biostatistics is the application of statistics to a wide range of topics in biology. The science of biostatistics encompasses the design of biological experiments, especially in medicine, pharmacy, agriculture and fishery; the collection, summarization, and analysis of data from those experiments; and the interpretation of, and inference from, the results. A major branch of this is medical biostatistics, which is exclusively concerned with medicine and health. Almost all educational programmes in biostatistics are at postgraduate level. They are most often found in schools of public health, affiliated with schools of medicine, forestry, or agriculture, or as a focus of application in departments of statistics. In the United States, where several universities have dedicated biostatistics departments, many other top-tier universities integrate biostatistics faculty into statistics or other departments, such as epidemiology. Thus, departments carrying the name "biostatistics" may exist under quite different structures. For instance, relatively new biostatistics departments have been founded with a focus on bioinformatics and computational biology, whereas older departments, typically affiliated with schools of public health, will have more traditional lines of research involving epidemiological studies and clinical trials as well as bioinformatics. In larger universities where both a statistics and a biostatistics department exist, the degree of integration between the two departments may range from the bare minimum to very close collaboration. In general, the difference between a statistics program and a biostatistics program is twofold: (i) statistics departments will often host theoretical/methodological research which are less common in biostatistics programs and (ii) statistics departments have lines of research that may include biomedical applications but also other areas such as industry (quality control), business and economics and biological areas other than medicine. The advent of modern computer technology and relatively cheap computing resources have enabled computer-intensive biostatistical methods like bootstrapping and resampling methods. Furthermore, new biomedical technologies like microarrays, next generation sequencers (for genomics) and mass spectrometry (for proteomics) generate enormous amounts of (redundant) data that can only be analyzed with biostatistical methods. For example, a microarray can measure all the genes of the human genome simultaneously, but only a fraction of them will be differentially expressed in diseased vs. non-diseased states. One might encounter the problem of multicolinearity: Due to high intercorrelation between the predictors (in this case say genes), the information of one predictor might be contained in another one. It could be that only 5% of the predictors are responsible for 90% of the variability of the response. In such a case, one would apply the biostatistical technique of dimension reduction (for example via principal component analysis). Classical statistical techniques like linear or logistic regression and linear discriminant analysis do not work well for high dimensional data (i.e. when the number of observations n is smaller than the number of features or predictors ). As a matter of fact, one can get quite high R2-values despite very low predictive power of the statistical model. These classical statistical techniques (esp. least squares linear regression) were developed for low dimensional data (i.e. where the number of observations n is much larger than the number of predictors ). In cases of high dimensionality, one should always consider an independent validation test set and the corresponding residual sum of squares (RSS) and R2 of the validation test set, not those of the training set. In recent times, random forests have gained popularity. This technique, invented by the statistician Leo Breiman, generates a lot of decision trees randomly and uses them for classification (In classification the response is on a nominal or ordinal scale, as opposed to regression where the response is on a ratio scale). Decision trees have of course the advantage that you can draw them and interpret them (even with a very basic understanding of mathematics and statistics). Random Forests have thus been used for clinical decision support systems.
