Q

Are the spread of values about the mean. Smaller dispersion of scores arising from the comparison often indicates more consistency and more reliability.

16
Q

It measures how far each number in the set is from the mean.

A

Variance

17
Q

It provides some idea about the distribution of scores around the mean (average).

A

Standard Deviation

18
Q

The blank the standard deviation, the more narrow the range between the lowest and highest scores or, more generally, that the scores cluster closely to the average score.

A
19
Q

Is data in the form of numbers. These numbers can be a count of objects, numbers, or any data which uses numbers.

A

Numerical Data

20
Q

Is non-numerical data that uses description/vocabulary, such as choice of colours, or choice of flavours.

A

Categorical Data

21
Q

What are the two types of numerical data?

A

discrete and continuous

22
Q

In statistics, it is quantitative data that can be counted, but not measured. The number of students in a class can be counted, and that is an example of blank.

A

Discrete

23
Q

Iss data that can take any value. Height, weight, temperature and length are all examples of continuous data. Some continuous data will change over time; the weight of a baby in its first year or the temperature in a room throughout the day.

A

Continuous

24
Q

Categorical Data is represented through

A

Pie Graph

25
Q

Continuous Data is represented through

A

Line graph or histogram

26
Q

Discrete Data is represented through

A

Bar graph

27
Q

What do you call the data collected in its original form?

A

Raw Data

28
Q

What is the formula to calculate the mean of a data set?

A

Sum of all values divided by the number of values

29
Q

The students’ favorite dessert is an example of what type of variable?

A

Nominal

30
Q

Which statistical measure provides information about how spread out the data set is from the mean?

A

Standard Deviation

31
Q

Data organized and summarized in the forms of frequency distribution.

A

Grouped Data

32
Q

Which type of data can be classified as discrete or continuous?

A

Numerical

33
Q

Which value represents the middlemost value in a data set?

A

Median

34
Q

Which measures of central tendency identify the central value of a data set?

A

Median, mode, and mean

35
Q

Which type of data can be counted or measured?

A

Numerical Data

36
Q

It represents categories or labels without any specific order. The categories are mutually exclusive, meaning they do not overlap, and there’s no inherent ranking between them.
Example:
Gender: Male, Female, Other
Blood type: A, B, AB, O
Colors: Red, Blue, Green

A

Nominal Data

37
Q

It represents categories that do have a specific order or ranking, but the intervals between the categories may not be equal. While the data can show relative ranking, it doesn’t provide precise differences between the ranks.
Example:
Education level: High school, Bachelor’s, Master’s, Doctorate
Customer satisfaction: Very dissatisfied, Dissatisfied, Neutral, Satisfied, Very satisfied
Military ranks: Private, Corporal, Sergeant, Lieutenant

A

Ordinal Data

38
Q

The most reliable measure of variability is

A

Standard Deviation
