What happens to the sampling distribution if we increase the sample size? As the sample size (n) gets larger, the sample means tend to follow a normal probability distribution As the sample size (n) gets larger, the sample means tend to cluster around the true population mean Holds true, regardless of the distribution of the population. 2% (n = 22) of the time. Calculate the sample mean. Although frequently confused, they are quite different. provides another reason for the importance of the normal distribution. Observations recorded during research constitute data. In terms of assessment, the value of Biostatistics lies in deciding what information to gather and the identified health problems, in finding patterns in collected data, and in summarizing and presenting these in an effort to best describe the target population. Continuous and discrete distributions i. A Likert scale is composed of a series of four or more Likert-type items that represent similar questions combined into a single composite score/variable. 60: The arrangement of data in rows and columns is called: (a) Classification (b) Tabulation (c) Frequency distribution (d) Cumulative frequency distribution.
