Data is a collection of facts, such as numbers, words, measurements, observations or just descriptions of things. Qualitative data describes a subject, and cannot be expressed as a number. Example: Your friends’ favorite holiday destination How people describe the smell of a new perfume Quantitative data defines a subject and is expressed as a number (it can be quantified) that can be analyzed Example: Number of people living in your town The height of Taruna Bakti’s students There are 120 people in your local football club. You can ask everyone (all 120) what their age is. That is a population. Or you could just choose the people that are there this afternoon. That is a sample. Population is when we collect data for every member of the group (the whole "population") Sample A Sample is when we collect data just for selected members of the group. HOME

MODE (the number which appears most often) HOME Height (cm) Total of students 150 3 152 4 154 2 155 2 To find out the mode of the data above, we don't use any formulas. We determine the mode only through observation. Based on the observation, the Mode is 152, as it occurs most often. Ten students were chosen as samples and their height was measured. The results of height measurements are as follows. 172, 167, 180, 170, 169, 160, 175, 165, 173, 170 Determine the mode of those data! To find out the mode of the data above, we don't use any formulas. We determine the mode only through observation. Based on the observation, 170 appears twice, all the rest appear only once, so 170 is the mode.
