3 Medical Mathematics: Introduction to Statistics (not done)

Question 0

What is Population?

Answer 0

Is an entire group of elements (observations) that have at least one thing in common such as the GPA of all students

Question 1

What is Statistics?

Answer 1

Is the science of assembling, classifying, tabulating, and analyzing data of a numerical kind so as to present significant information about a given subject

Question 2

What is a Sample?

Answer 2

Is a small group of elements selected from the total population such as the GPA of a student in one class

Question 3

What is a Parameter?

Answer 3

A characteristic of a population

Question 4

What is a Statistic?

Answer 4

A characteristic of a sample

Question 5

What is Data?

Answer 5

Is a collection of numbers (scores or measurements)

Question 6

What is Qualitative data?

Answer 6

is non-numeric data in narrative form

Question 7

What is Quantitative data?

Answer 7

Is numeric data.

Question 8

What is Measurement?

Answer 8

Assigning numbers to observations according to rules

Question 9

What is a Variable?

Answer 9

A measured characteristic that can have various values or levels

Question 10

What is Discrete variables?

Answer 10

Have only certain values (whole numbers)

Question 11

What is Continuous variables?

Answer 11

Can have any value either whole numbers or whole numbers and fractions (accuracy of measurement)

Question 12

What is Descriptive statistics?

Answer 12

Is a way of summarizing data such as when one number represents a group of numbers. Tables and graphs also can be used to summarize data

Question 13

SUMMARIZING DATA

Answer 13

1. Tabular representation of data
2. Graphical representation of data
3. Numerical representation of data

Question 14

Tabular Representation of Data

Answer 14

1. Frequency distribution
2. Cumulative frequency distribution
3. Grouped frequency distribution
4. Cumulative grouped frequency distribution

Question 15

Cumulative Frequency Distribution can be created from?

Answer 15

Can be created from a frequency distribution by adding and additional column called “cumulative frequency”.

Question 16

What is a histogram?

Answer 16

A histogram is similar to the bar graph but is used to represent data at the ratio or interval level of measurement, while the bar graph is used to represent the data at the nominal or ordinal level of measurement.

Question 17

What is a bar graph?

Answer 17

A bar graph is used to represent the data at the nominal or ordinal level.
The bars are separated by a space.

Question 18

What is Median?

Answer 18

The middle value when the number of data is odd and the mean of the middle two
values when the number of data is even

Question 19

What is Mode?

Answer 19

The most frequent value (there may be more than one mode or no mode)

Question 20

What is range?

Answer 20

The range is the difference between the highest score and the lowest score plus 1 for whole number data

Question 21

What is variance?

Answer 21

The variance is used to measure the deviation of the individual scores from the mean.
The variance is the average squared deviation of the scores from the mean

Question 22

What is standard deviation?

Answer 22

The standard deviation is the square root of the average squared deviation of the scores from the mean.
The standard deviation is the square root of the variance.
