Step-by-step explanation:
Q1:
Statistics are aggregate of facts, a single numerical fact can't be called statistics. Thus they only deal with groups and not individuals. Statistics only deals with quantitative data it does not deal well with qualitative data beauty, honesty, goodwil etc cant be measured.
Q2:
Statistical enquiry means statistical examination. The person who conducts an investigation is referred to as an investigator. The investigator requires the help of an enumerator who gathers data and a respondent who gives the information about statistical examinations.
Q3:
A schedule or a timetable, as a basic time-management tool, consists of a list of times at which possible tasks, events, or actions are intended to take place, or of a sequence of events in the chronological order in which such things are intended to take place.
Q4:
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency.
Q5:
By. n. in statistics, refers to a two-way frequency distribution which can be represented through a graph or table. Either way, the results of two random variables (e.g. weight versus height) can be simultaneously displayed.
Q6:
Bar diagrams are One-dimensional diagrams. ... These are represented on a plane of two axis and depicts the relationship between the two variables (plotted on the either axis) in form of rectangular bars.
Q7:
The major disadvantage of using charts and graphs is that these aids may oversimplify data, which can provide a misleading view of the data. Attempting to correct this can make charts overly complex, which can make their value in aiding a presentation less useful.
