Sample standard deviation for frequency table: = s n [ ∑ ( f • x 2 ) ] − [ ∑ ( f • x ) ] 2 n ( n − 1) Sample z-score: z = x − x s Population z-score: z −μ = x σ Interquartile Range: (IQR) = Q 3 − Q 1 Modified Box Plot Outliers lower limit: Q 1 - 1 5 (IQR) upper limit: Q 3 + 1 5 (IQR) |
What is a statistic in mathematics?
Statistics is a branch of mathematics which deals with numbers and data analysis. Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. Statistical theory defines a statistic as a function of a sample where the function itself is independent of the sample’s distribution.
Why is it important to learn statistical techniques & formulas?
Being able to make the connections between those statistical techniques and formulas is perhaps even more important. It builds confidence when tackling statistical problems and solidifies your strategies for completing statistical projects.
How do you test a statistical hypothesis?
To test a statistical hypothesis, you take a sample, collect data, form a statistic, standardize it to form a test statistic (so it can be interpreted on a standard scale), and decide whether the test statistic refutes the claim. The following table lays out the important details for hypothesis tests.
What are the basic statistics?
The basics of statistics include the measure of central tendency and the measure of dispersion. The central tendencies are mean, median and mode and dispersions comprise variance and standard deviation. Mean is the average of the observations. Median is the central value when observations are arranged in order.
