Statistics How To

Statistics definitions > Have you ever been stuck on a math problem that seemed impossible to solve? Sometimes, exact solutions to math problems are too difficult or expensive to calculate. That’s where numerical analysis comes in. Numerical analysis is a branch of mathematics used to approximate the solution of continuous problems using numeric approximation. In … Read more

Binomial Theorem > Binomial probabilities in Minitab How to Find Binomial Probabilities in Minitab Binomial probability is a way of calculating the probability of an event happening in a binomial trial (i.e. a trial with only two possible outcomes, like tossing a coin). How you find binomial probabilities in Minitab depends on which type of … Read more

Statistics Definitions > Mode Contents: What is the Mode? How to find the mode by hand How to find the mode using Excel Find the mode in Minitab What is the Mode? The mode, or modal value, is the most common number in a data set. It’s useful in statistics because it can tell you … Read more

F Ratio > Mean Square Between What is Mean Square Between? Mean square between gives you an idea of differences between sample means. It’s biggest use is to find the F ratio in an ANOVA test. Depending on the author, it is denoted by MS(B), σ2 or . On its own, MS(B)isn’t a very useful … Read more

Statistics Definitions > Location Parameter What is a Location Parameter? The location parameter tells you where your graph is located. More specifically, it tells you where on the horizontal axis a graph is centered, relative to the standard normal model. The standard normal distribution curve is centered at 0 (the mean), so a parameter of … Read more

Statistics Definitions > 10% Condition 10% Condition The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a … Read more

Descriptive Statistics > Unimodal Distribution Unimodal Distribution : Overview A unimodal distribution is a distribution with one clear peak or most frequent value. The values increase at first, rising to a single peak where they then decrease. The “mode” in “unimodal” doesn’t refer to the most frequent number in a data set (although it’s closely … Read more

Statistics Definitions > Large Enough Sample Condition The Large Enough Sample Condition tests whether you have a large enough sample size compared to the population. A general rule of thumb for the Large Enough Sample Condition is that n ≥ 30, where n is your sample size. However, it depends on what you are trying … Read more

Descriptive Statistics: Definition & Charts and Graphs > What is a House Graph? A house graph is a graph on 5 nodes and 6 edges, which is illustrated above in two embeddings. The name of this graph derives from its resemblance to a schematic illustration of a house with a roof. A house graph consists … Read more

Probability and Statistics > Basic Statistics > What is a Parameter in Statistics? This article is about population parameters. For the parameters you would use to define a probability distribution, see: What is parametrization? What is a Parameter in Statistics? In math, a parameter is something in an equation that is passed on in an … Read more
