are those data which are not yet organized or arranged into frequency distribution

Ungrouped Data or Raw Data

- This is what people usually intend when they say "average"

Mean

– is defined as sum of the values of a variable divided by the number of observations.

Arithmetic Mean

– Considers the proper weights assigned to the observed values according to their relative importance.

Weighted Mean

is the middle value of a set of data. It is the middle value when the data is arranged in an array (increasing or decreasing order)

Median

is the most frequently occurring value in the data set.

Mode

– there is only one mode from a set of data.

unimodal

there is two modes from a set of data.

Bimodal

– there is three modes in a set of data.

Trimodal

– there is 4 or more modes in a set of data

Multimodal

- if all the terms in a given data are occurred once only

No Mode

– to compute mean of grouped data, we need to determine the midpoint of each class interval. The mean assumed that the class mark is the average value of all items falling in that class.

Mean

– the median of a grouped data could be determined by the following

Median (Grouped)

– defined as the midpoint of the class interval with the highest frequency (modal class). The mode obtained is this manner is called a crude mode, because it is just a rough approximation of the actual mode. So, to determine the true mode, we use the formula

Mode (Grouped Data)
