Frequency Distribution (General)

frequency distribution

one of the most common procedures for organizing a set of data

frequency distribution

organized tabulation of the number of individuals located in each category on the scale of measurement

frequency distribution

takes a disorganized set of scores and places them in order from highest to lowest, grouping together individuals who all have the same score

frequency distribution

allows the researcher to see "at a glance" the entire set of scores

frequency distribution

shows whether scores are generally high or low, whether they are concentrated in one area or spread out across the entire range

frequency distribution

generally provides an organized picture of the data

frequency distribution

allows you to see the location of any individual score relative to all other scores in the set

set of categories / record of frequency in categories

frequency distribution shows 2 elements < (2/)

frequency distribution

presents a picture of how the individual scores are distributed on the measurement scale

frequency distribution table

presents measurement scale by listing the diff measurement categories (X values) in a column from highest to lowest

x values

these in a frequency distribution table represent the scale of measurement, NOT THE SET OF SCORES

frequency

can be used to find the total number of scores in the distribution

∑f = N

FORMULA

frequency to total scores

distribution, raw score

2 ways to present data: < (2,)

distribution

set of scores arranged for recording or study

frequency distribution

scores listed alongside the number of times each score occurred

raw score

straightforward, modified accounting of performance, usually numerical

simple frequency distribution

scores listed but not grouped

grouped frequency distribution

more convenient, easy-to-read summary of data, however it loses information

class intervals

these grouped replace the actual scores in grped frequency distribution

decrease zero value, when difficult to visualize shape, when difficult to have central tendency

why group? < (3,)

frequency distribution

can be used to describe the position of an individual within the set

x values

raw scores/individual scores

grouped frequency distribution

presenting groups of scores rather than individual values
