Chapter 3 - 🧠 ANSWER ✔✔DESCRIPTIVE STATISTICS, PROBABILITY,
AND MEASURE OF CENTRAL TENDENCY
descriptive Statistics - 🧠 ANSWER ✔✔computed to reveal characteristics of
the sample and to describe study variable
,How to describe a sample - 🧠 ANSWER ✔✔create a frequency distribution
of the variable or variable being studied
- is a plot of one variable, whereby the x-axis consists of possible values of
that variable , and the y - axis is tally of each value
Inferential Statistics - 🧠 ANSWER ✔✔computed to draw conclusions and
make inferences about the greater population, based on the sample data
set.
Bi Modal - 🧠 ANSWER ✔✔having or providing two modes, ,methods,
systems, etc.
-having 2 values/categories that have highest occurrence and are equal
frequencies
Central Tendency - 🧠 ANSWER ✔✔indicator of center of data
-nominal variable= categorical differences EX: gender (tendency of
samples of given measurement to cluster around some central value.
Measures of Central tendency are descriptive statistics.
, Statistics represent measures of central tendency are mean, median and
mode (all are representations or descriptions of the center or middle of a
frequency distribution
mean= arithmetic average of all of the values of a variable.
median= exact middle value ( or average of the middle two values if there
is an even number of observations)
mode= most commonly occurring value in a data set. can have more than
one mode in a sample.
in a normal curve, mean, median and mode are equal or approximately
equal
Multimodal - 🧠 ANSWER ✔✔having more than 2 modes
Unimodal - 🧠 ANSWER ✔✔When distribution only has one mode
-the frequencies progressively decline as they move away from the mode.
Symmetrical distributions are usually uni modal.
bimodal - 🧠 ANSWER ✔✔means you have not defined your population if
you find a bimodal
