Use the graphing calculator function Norminv(cut-off, mean, std. dev.) 4. Normal Sampling and Modeling. a) If a sample of a population has been given use the sample mean and sample standard deviation, then use the z-score method. b) If discrete data is being used it is permissible to use the standard z-score, but remember to use a continuity ...

z score between two numbers

Activity overview:
The x-value with a z-score = 0. The x-value with a z-score = –3. The x-value with a z-score = 2. A Graphs page and Calculator page can be can be used to find the exact corresponding percentiles and x-values when given z-scores. Problem: Find the corresponding percentile and x-value that has a z-score = –2.3 with mean = 100 and standard ...

https://info.5y1.org/z-score-graph-calculator_1_03b501.html
An effect size is exactly equivalent to a ‘Z-score’ of a standard Normal distribution. For example, an effect size of 0.8 means that the score of the average person in the experimental group is 0.8 standard deviations above the average person in the control group, and hence exceeds the scores of …

Ex: goals, score, time. Dot plots – for quantitative data. X= Goals per game Y= Number of times that occurred (frequency) Stem plots – Quick picture of the shape of the distribution while also including numerical values. Use for SMALL data sets!! You can double the number of stems therefore reducing the number of leaves.
