Answers
Answer:
ARRAY-An array is a container object that holds a fixed number of values of a single type.
OBSERVATION-In probability and statistics, a realization, observation, or observed value, of a random variable is the value that is actually observed (what actually happened).
TABULATION- The process of placing classified data into tabular form is known as tabulation.
TALLYMARKS-Tally marks, also called hash marks, are a unary numeral system. They are a form of numeral used for counting.
PRIMARY DATA-Primary data is information that you collect specifically for the purpose of your research project.
SECONDARY DATA-Secondary data refers to data which is collected by someone who is someone other than the user.
RANGE-The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.
MEAN-The statistical mean refers to the mean or average that is used to derive the central tendency of the data in question.
MEDIAN-For a continuous probability distribution, the median is the value such that a number is equally likely to fall above or below it.
MODE-The mode of a set of data values is the value that appears most often.[1] It is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
