It is used to measure the chi-square test. For measuring the chi-square test there are two conditions: 1.Variables should be measured in nominal or ordinal level. 2. Variables should contain two or more categorical or independent groups. For example, to teach statistics for undergraduates,educators have to know their auidence(male,female) and which mode of learning they want(online,offline).So,here two nominal variables gender and medium of learning. Steps how to do chi-square in SPSS using cross-tabulation: Step1:  Referring to the above examples, two variables are gender,medium of learning.

It is used for only for counting purposes. 2.Ordinal: It is the second level of measurement in which ranking of data without actually establishing the degree of variation between them. Likert Scale through which we can measure the order. Scale: Divided into two parts: 1. Interval Scale 2. Ratio Scale 1.Interval Scale: In this measurement variables are measured in exact manner not in relative manner. Example: Likert Scale Net Promoter Score(NPS) Bipolar Matrix Table 2.Ratio Scale It allows researchers to compare the differences or intervals. The ratio scale has a unique feature. It possesses the character of the origin or z
