It can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
(a)
It is the average of the data that is being collected.
(a)
Type of probability often referred to as the "priori" or "theoretical probability".
(a)
It shows the range of possible outcomes and their relative likelihood of occurrence.
(a)
It is a summary measure that attempts to describe a whole set of data with a single value.
(a)
A type of probability which considers an individual's own belief and feeling and not on a formal mathematical calculation.
(a)
It is the middle value of the data.
(a)
A type of probability where the chances of occurrence or non-occurrence of any event can be quantified by the applications of axioms.
(a)
It is the most commonly occurring value.
(a)
A (a) is a kind of average. Instead of each data point contributing equally to the final mean, some data points contribute more "weight" than others.
A table with two columns. One column lists the categories, and another column gives the frequencies.
(a)
These are the pieces of information that allow us to classify the items under investigation into various categories.
(a)
A type of mean that is formerly sometimes called the subcontrary mean and is one of several kinds of average.
(a)
A type of mean that is defined as the positive root of the product of observations.
(a)
In a frequency distribution, what do you call the class with the highest frequency?
(a)
A mean can be determined by inspection.
TRUE
FALSE
In graphing pie chart, to find the angle of each “slice” takes up, we need to multiply the relative frequency of that slice by 330°.
TRUE
FALSE
A single coin on tossing has two outcomes.
TRUE
FALSE
The median is determined by sorting the data set from lowest to highest values and taking the data point in the middle of the sequence.
TRUE
FALSE
The joker, jack, the queen, and the king are called face cards.
TRUE
FALSE
In histogram, classes should have the same width and classes should not overlap.
TRUE
FALSE
Mode is readily comprehensible and easy to calculate.
TRUE
FALSE
Geometric mean is defined as the negative root of the product of observations.
TRUE
FALSE
To construct a bar graph, we need to draw a vertical axis, a horizontal axis and diagonal axis.
TRUE
FALSE
The mode is a good choice for a measure of central tendency when the data has many identical data values.
TRUE
FALSE
Drawing from a deck of cards has 52 total favorable outcomes.
TRUE
FALSE
The total number of outcomes on rolling two dice is 12.
TRUE
As compared with mean, mode is affected to a great extent by fluctuations of sampling.
TRUE
FALSE
There may be No Mode or only one mode.
TRUE
FALSE
Median is not affected by extreme values.
TRUE
FALSE
It is the frequency divided by “n”, the size of the sample. This gives the proportion of the entire data set represented by each value or class.
