Document Summary
F - number of times each score is seen in data. Y-axis f values definition: a single number that defines the centre of the distribution (to represent the entire group) Measures of central tendency: mode most frequent score; it appears at the highest peace in a table or graph. This is not very reliable and not very precise. Some distributions can have more than one mode. Bimodal = 2 mode; multimodal = >2 modes. X_ sum of all scores, divided by the number of scores in the data midpoint of the scores in the distribution when the scores are smaller to highest. 3, 3, 4, 5, 7, 8 median = 4+5/2 = 4. 5. Note: if you know the mean and the number of individuals, you can determine to total amount. The mean is a balance point int he frequency distribution (total distance below = total distance above)
