List and explain the differences between the 3 types of Longitudinal Studies – using your OWN words
A longitudinal study is a correlational research method that helps discover the relationship between variables in a specific target population. It is pretty similar to a cross-sectional study, although in its case, the researcher observes the variables for a longer time, sometimes lasting man years. The three main types of longitudinal studies are: panel study, retrospective study, and cohort study. These methods help researchers to study variable and account for qualitative and quantitative data from the research sample. A panel study is primarily designed for quantitative research, although you can use this method for qualitative data analysis. It helps you identify the causal factors of changes in a research sample.
The Egyptians as expressed were that exceptional as the Babylonians. They just utilized expansion and deduction do what should have been finished. For increase, they utilized the multiplying framework. For instance, on the off chance that they had to know what 12×2 was, they would simply add 12+12 to get 24, which is right. Concerning divisions, they utilized the amount of unmistakable portions, for instance ¾= ½ + ¼. Despite the fact that the Egyptians didn’t have the information for round estimation didn’t mean they couldn’t make it happen. They needed to figure out how to do so in light of the fact that once more, the water systems frameworks should have been first class a direct result of yearly flooding of the Nile Stream. For Instance, suppose they expected to track down the region of a circle with a breadth of 9. They saw the number 9 was extremely near the number 8. Thus, they could only numerous 9 x (8/9) and afterward square it, giving a wiggle room of short of what one percent.
I continue onward endlessly about the water system frameworks and how it integrates with the Nile stream’s yearly flooding that I continue disregarding the schedules and how they utilized math to sort out the place of the stars to make yearly ideas like, “new year’s” and things of that sort. The Egyptians utilized math to look and make times while estimating the ascent and fall of the Nile. They began their day At the crack of dawn and separation the day into 12 hours. In spite of the fact that it was exact, it was sufficiently precise to permit them to keep away from, once more, the flooding consequently permitted them to develop crops and made extraordinary sustention for a long time.
The Egyptians and the Babylonian math had numerous distinctions however they additionally had similitudes like the idea of common sense and utilizing their numerical abilities to additional better their social orders. This assists me with considering how all inclusive current math is. Whether it be hypothetical or applied, math can in a real sense be utilized in any field, even human expression, numerous craftsmen were referred to be keen on science too. So facetiously, I contribute that mathematicians are craftsmen too. We should get to the principal motivation behind why I’m in any event, composing this article: Mohammed al-Khwarizmi.
Mohammed al-Khwarizmi was a Persian mathematician who upset variable based math with his book, Hidab al-jabr al-muqubala in which he utilizes Hindu-Arabic numerals. As a result of his starting points, present day-Uzbekistan, it’s just normal he be impacted by the Babylonians and the Indians. The name addresses the two activities he partakes in his book. Al-jabar is Arabic for rebuilding and al-muqabala implies adjusting, in this way deciphering the title of the book to, The Concise Book on Computation by Fulfillment and Adjusting. From this book comes the idea of adding and oppressing, and the exchange of one term from one or the other side of a situation, subsequently the adjusting part. It begins with the delivering of a thought of conditions to the first and second degree. Then towards the end, starts the use of such thoughts.
His book, The Inclusive Book on Estimation by Finishing and Adjusting,
