study about dependent variable

A set of observations is called a called a collection of data. These observations should possess some common characteristics. They are recorded and used for further study. The quantities such as age, height and number of students are called variables..

By the study of electronic configuration of transition metals it is understood that variable oxidation state can be formed as there are both ns and (n-1)d electrons in bonding. The participation of ns electrons in bonding leads to +2 oxidation state which is a lower oxidation s..

Consider an example. A person was asked to measure the thickness of a coin. He recorded the following readings: (i) 0.2 cm with ruler (ii) 0.23 cm with vernier (iii) 0.231 cm with micrometer The accuracy of thickness of the coin depended on the instrument used for measuring the thickness..

The amount spent by Chris on a birthday party is a function of number of his friends whom he invited. Which of the following is a dependent variable? => Chris′s age or number of members in Chris′s family or number of friends Chris invited or amount spent by Chris on ..

Summary - Strength of an acid depends on the concentration of hydronium ions present in a solution. Greater the numbers of hydronium ions present, greater is the strength of the acid. A strong acid dissociates completely in water. Example: Hydrochloric acid A weak acid dissociates only pa..

Thermodynamic Variables or Parameters - Thermodynamic variables are the quantities like pressure, volume and temperature, which help us to study the behavior of a thermodynamic system. There are some other thermodynamic variables such as entropy, internal ene..

Thermodynamic variables are the quantities like pressure, volume and temperature, which help us to study the behavior of a thermodynamic system. There are some other thermodynamic variables such as entropy, internal energy, etc., but these thermodynamic var..

For any specific value of the independent variable, the values of the dependent variable y are normally distributed. This is called the __________ assumption. => independence or linearity or equal - variance or normality..

A function is described by the equation f ( x ) = 2 x + 1. The replacement set for the independent variable is {0, 2, 3, 4}. Which of the following is contained in the corresponding set for the dependent variable? => 9 or 2 or 3 or 15..

A function is described by the equation f ( x ) = x + 1. The replacement set for the independent variable is {1, 3, 5, 7}. Which of the following is not contained in the corresponding set for the dependent variable? => 6 or 10 or 8 or 4..
