Question

Discuss, sample size, measurement scale and multiple regression and their importance in research

Answer 1

1. Sample size

Discuss about Sample size it is used in research for conclusion or get feedback from people or groups to understand their thinking and observation about specific thing, that's why in Sample size choose some group of people in specific Size, Age, Education geographical area, Population, Subject with the help of this component researcher choose the sample size for research.

Importance of Sample size –

is very important in research because, if have to do research on Whole Population as sample or Maximum components, so it is not possible, but with the help of sample size we can Sample size analysis research results,

For example –

If have to analysis, western culture, then we can't take whole population for research because, it is not possible to do research on Whole Population, that's why researcher randomly select people as a sample size, and do research on it and get conclusion or results, so simply sample size help to researcher, analysis result huge components with choose less components.,

2. Measurement scale

In research Measurement scale used for Define and categorized a number and variables, measurement scale used for understanding the numbers and variables, People, Objects, event in meaningful way,

Important of Measurement Scale –

Measurement scale importance is to understand world cause in measurement scale measured time, distance, writing accuracy all these things measured to understand world around us for get results in Research.

Also importance of measurement scale if any decision have to take about certain things then measurement scale play important role to understand these things.

For example - Shape

3. Multiple regression

Multiple regression is Extension of Simple liner regression, it is used for predict or identify value of variable which is based on two or more variables to understand or predict it.

For example - you have to predict rainfall then in multiple regression have to identify or study of weather, environment, area

Importance of Multiple Regression –

Multiple regression importance in research it is help to researcher to understand how much dependent variable change in which change the independent variable and how much GPA need are expecting to enhance for every one point increase or decrease, so with the help of multiple regression we can identify this things that's why it is important.

Importance of multiple regression is Research and can compare independent variables with dependent variable for getting results.
