What are the effects of repeated exposure to an advertising message? The answer may depend on both the length of the ad and how often it is repeated. And experiment investigated this question using undergraduate students. All students viewed a 40 minute television program that included ads for a new smartphone. Some subjects saw a 30-second commercial others, a 90-second commercial. The same commercial was shown either one, three, or 5 times during the program. After viewing, all students answered questions about there recall of the ad, their attitudes towards the smartphone, and there intentions to purchase it. In this experiment, the length of the commercial and the number of times it was shown are. (A) the responses. (B) the blocking variables. (C) lurking variables. (D) the explanatory variables.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
