Statistics

A significant difference refers to a statistically meaningful distinction between two or more groups or variables. It implies that the difference observed is unlikely to have occurred by chance and is likely to have practical relevance. Statistical tests are used to determine if a difference is significant.

The number one day to suffer a heart attack is Monday, with research showing that there is a higher incidence of heart attacks at the beginning of the week. This may be attributed to the stress and anxiety associated with returning to work or school after the weekend.

A graph typically represents quantitative data using points, lines, or bars, while a chart is a visual representation of data that can include graphs, tables, or diagrams. Graphs are used to show relationships or trends in data, while charts are more general tools for visualizing information.

An attorney may become very involved in statistical analyses, although it is generally the use of statistical analyses as presented in the court room rather than the actual calculation of statistics. The presentations are done by expert statisticians or experts in related fields (public health, enviromental sciences, epidemiologists, bioinformation (DNA) scientists to name a few). Attorneys may be involved in issues of public health. For example, a company is suspected of contaminating the ground water. A class action suit is launched against the company. The attorney must show through presentations that there is good evidence of harm and the pollution is traceable to the company. The adequacy of sampling data will certainly be an issue. I did not find good websites on this topic, but there are some recent books. These are the ones I found: http://www.amazon.com/Statistics-Law-Morris-H-DeGroot/dp/0471055387 http://www.columbia.edu/~bl6/sflrev.htm Discrimination cases may also require statistical analyses. This link provides a description of books related to this topic. https://www.air.org/publications/documents/statbooks.pdf

As of 2021, there are approximately 56,000 statisticians employed in the United States, according to the U.S. Bureau of Labor Statistics.

As of the latest data available, there are approximately 33 million people employed in the UK. This number includes both full-time and part-time workers across various industries and sectors in the country.

Sir Ronald Aylmer Fisher, FRS (1890 - 1962) was an English statistician, evolutionary biologist, and geneticist. Richard Dawkins described him as "The greatest of Darwin's successors", and the historian of statistics Anders Hald said "Fisher was a genius who almost single-handedly created the foundations for modern statistical science".His contributions to experimental design, analysis of variance, and likelihood based methods have led some to call him "The Father of Statistics".

Deviation from statistical norms tends to rely on the rarity of a behaviour, so if a behaviour is rare in a population then it is statistically abnormal, but how rare is rare? For many statisticians any behaviour that lies beyond 2 standard deviations either side of the mean "fits the bill" (why shouldn't we go for three). Confused, well it can mean that if less than 5% (alright 2 SD's isn't exactly 5% its close enough!) of people are doing a particular behaviour then it is classed as abnormal, about 1% of the world population talks to people who aren't there so schizophrenia fits this definition; be careful though when looking at behaviours that might be normally distributed, intelligence perhaps, you can be abnormal by falling into the top 2.5%, e.g.IQ over 130 or the bottom 2.5%, IQ below 70, so you can be abnormal by doing too little or too much of a behaviour.

Deviation from social norms differs in that it doesn't matter how many people are doing the behaviour; its simply the kind of behaviour that this society will not put up with, so there could be 49% of the population breaking social norms, of course once you get over 50% those people will dictate the new social norm, so the behaviour would become a new norm and now the other group who didn't do the behaviour will break the social norm, of course they might try appealing to some "text" that lists a moral code that they think is universal. Victorian women might have seen premarital sex as bad or immoral, and yet in a modern western society the norm may now be the complete reverse. Try reading Szasz's views on masturbational insanity, witchcraft or homosexuality

If confused behaviours that appear odd or weird fit the statistical definition, whereas if the behaviour is immoral, bad, sick or possibly evil it probably breaks social norms, many "mental illnesses" fit more than one definition

The percentage(s) of the pros/pluses , and the cons/risks of measuring anything of importance that may aid in making a decision. This can include the taking of medicines that may or may not aid a condition. Or the studying of a college course and how it may affect a job promotion, monetary gain, or become more available, because of taking the course.

Pilot Survey: a preliminary piece of research conducted before a complete survey to test the effectiveness of the research methodology. This should be completed before the final survey commences. The intention is to alert the surveyor to any difficulties that were not anticipated at the survey proposal stage. Pilot surveys are undertaken after pre-tests.

The formula for calculating maternal mortality rate is: (Number of maternal deaths in a given period / Number of live births in the same period) x 100,000. This rate is used to measure the risk of death due to complications from pregnancy or childbirth.

A point estimate is a single value used to estimate a population parameter, such as the sample mean used to estimate the population mean. Confidence intervals can also be used to provide a range within which the population parameter is likely to lie.

The census surveys all members of the population. If the objective of the survey is to find representative values of certain attributes, say how much does the average fisherman make in Alaska, then certainly a survey that includes all fisherman should be more accurate. If all members of the population are surveyed, then the resultant summary values would be considered parameters rather than statistics. For example:no statistical inference is made if I state there are 1,000 fisherman in Alaska, and a tally of all of them, shows their average income is $20,000. I can say that a census should be more accurate than a sample survey, provided all other factors are the same and precautions are taken to obtain reliable data. A census conducted in a biased manner will not provide accurate parameters.

Colorado ranks 8th in size among the 50 states, with a total land area of approximately 104,094 square miles.

The mean is used to measure the average of a set of values, especially when the data is normally distributed. The median is used to find the middle value of a dataset when there are extreme values or outliers present, as it is less affected by extreme values.

A census is a statistical enumeration and analysis of a certain population, be it humans, animals or plants - groups that grow and change over time.

A survey can be a tally of opinions or answers. See "Family Feud" when Richard Dawson says, "Survey says...!!!!"

Survey participation rate is calculated by dividing the number of people who completed the survey by the total number of people invited to participate, and then multiplying the result by 100 to get a percentage. The formula is: (Number of completed surveys / Number of invited participants) * 100.

132. You're the the one that stated "normal distribution", thus the same.

As of 2021, there are approximately 224 million households in Europe. This number can vary slightly depending on the source and how households are defined.

Briefly, the variance for a variable is a measure of the dispersion or spread of scores. Covariance indicates how two variables vary together.

The variance-covariance matrix is a compact way to present data for your variables. The variance is presented on the diagonal (where the column and row intersect for the same variable), while the covariances reside above or below the diagonal.

The correlation coefficient is zero when there is no linear relationship between two variables, meaning they are not related in a linear fashion. This indicates that changes in one variable do not predict or explain changes in the other variable.

Ecologists can estimate population size through methods such as mark-recapture, distance sampling, and census surveys. Mark-recapture involves capturing and marking individuals, releasing them, and then recapturing a sample to estimate total population size. Distance sampling involves estimating population size by observing and recording the distances to individuals from a specific vantage point. Census surveys involve conducting a thorough count of all individuals in a specific area.
