Multi-… approaches in statistics. Multiple comparison tests. Multiple testing adjustments. Methods for adjusting the significance levels when doing a large number of tests (comparisons between treatments) within a single analyses. Types of Variables. There are 2 main types of variables: . Independent Variable: . The variable that is changed by the scientist; the ‘. I control. ’ variable. Dependent Variable: . The variable that might change because of what the scientist changes – what is being measured . Data types, variable declaration, and initialization. Type. Size. Use. Int. 4 bytes. Integer. Long. 8 bytes. Bigger Integer. Float. 4 bytes. Decimal values. Double. 8 bytes. Precise. decimals. TOO MANY DATA TYPES!!. Introduction to Value types and Reference types. Simply put. Reference types store data in the memory address of the variable itself. Reference types store a 32 bit (or 64 bit) pointer to another object. By. Shyam. . Gurram. Variables. Variables: There are certain rules for variables. A variable starts with the $ sign, followed by the name of the variable. A variable name must start with a letter or the underscore character.

Data types - specifies the kind of data you are storing. 1. Outline:. The contingency table. Independence and dependence. Hypothesis test for independence. The chi-square distribution. The “expected” table. The test statistic. Worked example. Categorical variables. 3. Introduction. The primary interest in data analysis is usually in . relationships. between variables.. The most . useful numerical summary . measure is correlation.. The most useful graph is a scatterplot.. Objectives. Work with numeric data. Describe the difference between value types and reference types. Declare and use variables to store data. Create constants. Write expressions containing arithmetic operators and operands.
