"What is a psychological test?" is a test item that is likely to appear in

Achievement Test

Post-test is an example of

Multiple tests

Test battery refers to

Individual

____ testing inevitably involves a great deal more preparation and usually requires supervised experience than group testing.

group

Individual testing inevitably involves a great deal more preparation and usually requires supervised experience than ___ testing.

Paper and pencil tests

Local testing is another term for

Median

Middle score in the distribution

Appropriate for: ordinal, interval and ratio.

Used when the distribution is skewed and when there are outliers.

Median

Middle score in the distribution

Median

Appropriate for: ordinal, interval and ratio.

Median

Used when the distribution is skewed and when there are outliers.

Median

The ____ represents the middle score in the distribution.

We arrange the data set in ascending or descending order and find the middle value.

If the data set has an odd number of values, the median is easy to locate.

ascending or descending

In Median, we arrange the data set in ______ order and find the middle value.

odd

In Median, if the data set has an ___ number of values, the median is easy to locate.

even

However, if the data set has an ___ number of values, there will be two middle values. To determine the actual median, you need to calculate the mean of these two values

Median

The ____ is appropriate for ordinal, interval, and ratio data.

The ___ is best used when the distribution is skewed due to the presence of outliers.

The ____ is not sensitive to outliers, meaning that even if there are extreme values, the median remains unchanged.

ordinal, interval, ratio

The median is appropriate for _________ data.

skewed

The median is best used when the distribution is ____ due to the presence of outliers.

outliers

The median is not sensitive to ____, meaning that even if there are extreme values, the median remains unchanged.

Ordinal

it is something that we can arrange in order.

Mode

The most frequently occurring score (common or typical)

Can have more than one mode

The only central tendency that can be used in nominal / categorical data

Mode

The most frequently occurring score (common or typical)

Mode

Can have more than one

Mode

The only central tendency that can be used in nominal / categorical data

Mode

Most frequently occurring value

Mode

It can be bimodal (2 peaks), trimodal (3 peaks), or multimodal (many peaks).

Mode

We can have more than one ___.

Bimodal

2 peaks

Trimodal

3 peaks

Multimodal

many peaks

A distribution with only one peak is called

Major Mode

In bimodal, the higher peak is called the

Minor Mode

In bimodal, the lower peak is called the

Mode

It is also possible for a data set to have no

In central tendency, the measure we use depends on the type of data set or the distribution of the data.

Skewness

The nature of and extent to which symmetry is absent

Proportion of higher vs lower scores

Piling of one score on one side.

Skewness

The nature of and extent to which symmetry is absent

Skewness

Proportion of higher vs lower scores

Skewness

Piling of one score on one side.

Skewness

refers to the proportion of higher vs. lower scores or the absence of symmetry.

Skewness

In the context of ____, we cannot make conclusive statements like:

Example: "Most of the students in the sample got high conscientiousness scores, and very few students got low conscientiousness scores." - This statement is too conclusive.

Instead, we might say:

"The majority scored higher than others, while only a small portion of the sample had lower scores."

Tail

In skewness, we focus on the ___ of the distribution.

negatively skewed

If the tail is thinner on the negative side, it is _____

positively skewed

If the tail is thinner on the positive side, it is ____.

Positively Skewed

Right skewed

Relatively few of the scores fall at the high end of the distribution

Greater portions of lower scores

Positively Skewed

Right skewed

Positively Skewed

Relatively few of the scores fall at the high end of the distribution

Positively Skewed

Greater portions of lower scores

Positive Skewed

The tail here is skewed positively or positive.

It extends toward the positive end of the x-axis.

Positively Skewed

You will observe that the mode is less than the median, which is less than the mean.

Negatively Skewed

Left skewed

Relatively few of the scores fall at the low end of the distribution

Greater proportions of higher scores.

Negatively Skewed

Left skewed
