IDK know th answer sorry pls
Answer:
(a) RAW DATA : Raw data, also known as primary data, is data (e.g., numbers, instrument readings, figures, etc.) collected from a source. In the context of examinations, the raw data might be described as a raw score.
(b) GROUPED DATA : Grouped data are data formed by aggregating individual observations of a variable into groups, so that a frequency distribution of these groups serves as a convenient means of summarizing or analyzing the data. There are two major types of grouping: data binning of a single-dimensional variable, replacing individual numbers by counts in bins; and grouping multi-dimensional variables by some of the dimensions (especially by independent variables), obtaining the distribution of ungrouped dimensions (especially the dependent variables).
(c) OBSERVATION : An observation in statistics is a value of something of interest you're measuring or counting during a study or experiment: a person's height, a bank account value at a certain point in time, or number of animals.
(d) RANGE : In statistics, the range of a set of data is the difference between the largest and smallest values. It can give you a rough idea of how the outcome of the data set will be before you look at it actually [1] Difference here is specific, the range of a set of data is the result of subtracting the smallest value from largest value.
(e) CLASS MARK : The class midpoint (or class mark) is a specific point in the center of the bins (categories) in a frequency distribution table; It's also the center of a bar in a histogram. It is defined as the average of the upper and lower class limits.
(f) CLASS SIZE : Class size is the average number of students per class, calculated by dividing the number of students enrolled by the number of classes.
