Descriptive Statistics Descriptive statistics involves organizing, summarizing and illustrating statistical data. The objective is to show important characteristics of the data without drawing any conclusions. Inferential statistics involves using a representative subset of data (a sample) in order to draw conclusions about unknown characteristics of an entire set of data (a population). Population: The entire

where the probability of selection can't be accurately determined. It involves the selection of elements based on assumptions regarding the population of interest, which forms the criteria for selection. Hence, because the selection of elements is non-random, non-probability sampling does not allow the estimation of sampling errors. These conditions give rise to exclusion bias, placing limits on how much information a sample can provide about the population. Information about the relationship between

Intelligence and Ability Paola Barrios Florida International University Abstract A study was performed using 3 different surveys reflecting one of three patterns. The first was “Improves”, the second was “Worsens”, and the third was “Random”. Using these 3 surveys, 123 participants were observed while they made changes to the responses on their paper. The participants were asked to mark the right answer on the first page as the researcher spoke the letters to each question. After
