Document Summary
Report on the status of variables- with numbers. In quantitative research we think about how variables effect outcomes of things we are testing. How does gender, age, experience, ethnicity, etc impact our outcomes. Indicate the number of individuals who receive each possible score on a variable. Represents frequency distribution of continuous variables (so there are ranges of scores that are continuous and then it indicates how many instances fell in that bucket ) Bar graphs don"t have to be a continuous variable. Obtained by adding all the scores from a sample and dividing by the number of scores. Score that divides the group in half by finding the midpoint. Must reorder the number set into lowest to highest rank. Reduces the influence of outliers or extreme cases. Variability: amount of spread in the distribution of scores (how different are the scores from one another) Calculation that determines the average variability of all scores from the mean.
