Describing Distributions in Statistics
 
12:56
The four key points are discussed when describing distributions in statistics...Shape, Center, Spread, and Outliers. Please forgive the misspelling of DESCRIBED in the video. TIP to identify Left & Right Skewness: (Thanks LeBadman:) Left: Mean is less than Median is less than Mode Symmetrical: Mean, Median and Mode are approximately equal Right: Mean is greater than Median is greater than Mode You just take: Mean, Median, Mode If it's left skewed, you will see the inequalities pointing to the left. If it's right skewed, you will see the inequalities pointing to the right.

Normal Distribution - Explained Simply (part 1)
 
05:04
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

Describing the Shape, Center, and Spread of a Distribution
 
08:36
This statistics lesson shows you how to describe the shape, center, and spread of the distribution by just examining the graph of the data given by a histogram or a dotplot. By inspecting the graph of a distribution, you could identify important statistic and behavior of your data by how the density curve forms it shape.

Summarize and describe the distribution of a categorical variable in context. Generate and interpret several different graphical displays of the distribution of a quantitative variable (histogram, stemplot, boxplot). Summarize and describe the distribution of a quantitative variable in context: a) describe the overall pattern, b) describe striking deviations from the pattern. Relate measures of center and spread to the shape of the distribution, and choose the appropriate measures in different contexts. Apply the standard deviation rule to the special case of distributions having the "normal" shape. Explore relationships between variables using graphical and numerical measures. Classify a data analysis situation (involving two variables) according to the "role-type classification," and state the appropriate display and/or numerical measures that should be used in order to summarize the data. Compare and contrast distributions (of quantitative data) from two or more groups, and produce a brief summary, interpreting your findings in context. Graphically display the relationship between two quantitative variables and describe: a) the overall pattern, and b) striking deviations from the pattern. Interpret the value of the correlation coefficient, and be aware of its limitations as a numerical measure of the association between two quantitative variables. In the special case of linear relationship, use the least squares regression line as a summary of the overall pattern, and use it to make predictions. Recognize the distinction between association and causation, and identify potential lurking variables for explaining an observed relationship. Recognize and explain the phenomenon of Simpson's Paradox as it relates to interpreting the relationship between two variables. Sampling. Examine methods of drawing samples from populations Identify the sampling method used in a study and discuss its implications and potential limitations. Designing Studies. Distinguish between multiple studies, and learn details about each study design. Identify the design of a study (controlled experiment vs. observational study) and other features of the study design (randomized, blind etc.). Explain how the study design impacts the types of conclusions that can be drawn.

I do not do any calculations in this video, or discuss the probability mass functions or other characteristics of the distributions. This video is simply an overview of the distributions that can either be used as a summary recap, or a quick introduction.

After differentiating between discrete and continuous variables, we begin to examine the wide range of probability distributions that apply to discrete variables. The properties and applications of the bivariate, the binomial, the poisson, and the hypergeometric probability distributions are studied.

How to detect outliers in SPSS
 
07:52
I describe and discuss the available procedure in SPSS to detect outliers. The procedure is based on an examination of a boxplot. SPSS can identify two different types of outliers, based on two different inter-quartile range rule multipliers. Neither multiplier (1.5 and 3.0) is ideal, however, with a bit of extra work, you can calculate an outlier based on the 2.2 multiplier. I demonstrate how to do so here: https://www.youtube.com/watch?v=WSflSmcNRFI

Species Distributions
 
10:32
This video is designed to prod the non-science student into thinking about various ecological factors that might limit the distribution and abundance of a given species. This video was constructed specifically for use with the case study titled "Crazy About Cryptids! An Ecological Hunt for Nessie and Other Legendary Creatures" by Matthew P. Rowe, Department of Integrative Biology, Michigan State University. This entire case study can be found on the National Center for Case Study Teaching in Science website at the following address: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=779&id=779 Running time: 10:32. Produced by Matthew Rowe in association with The National Center for Case Study Teaching in Science and Michigan State University, 2015.
Statistics - How to make a relative frequency distribution
 
04:38
This video covers how to make a relative frequency distribution chart. Remember that in a relative frequency distribution we scale back the frequency using the total frequency. Depending on rounding, the total relative frequency might not be one, but should be very close. For more videos please visit http://www.mysecretmathtutor.com

Statistics - Module 7 Video 1- Sampling and Sampling Distributions
 
05:37
Go to http://statisticsworkbook.com/ to download the problems. Module 7 covers the topic of sampling distributions. We will first consider the differences between sampling from a finite versus and infinite population. This is followed by a few examples of point estimation for both a population mean and a population proportion. We then examine the sampling distributions of sample means and sample proportions. In both scenarios, we study expected values, standard deviation, variance and the relationship between sample size and sampling distribution.
