In a standard normal curve, the mean, median and the mode is __________.

• equal

• not equal

• greater than

• less than

It measures the distance between an observation and the mean, measured in units of standard deviation.

• standard score

• area

• probability

• normal curve

The normal curve is divided into ±3 standard deviation.

• True

• False

The tails of the curve are asymptotic relative to the vertical line.

• True

• False

The histogram of the sampling distribution of the sample means is constructed by where the sample means are plotted on the vertical axis and the corresponding probabilities.

• True

• False

In this sample, the sample is selected without order and members do not have an equal chance in being part of the sample.

• Probability Sampling

• Non-Probability Sampling

The members in the population are listed in systematic ways and are selected at equal intervals from the starting point.

• Stratified

• Systematic

• Random

• Cluster

The sample is selected based on the objective or purpose of the study.

• Cluster

• Snowball

• Purposive

• Referral
