which term represents the most frequent score in a frequency distribution course hero

What is a frequency distribution in statistics?

A frequency distributionshows the number of times each score (in this case, the number of yards) is obtained. We can tell at a glance that these two distributions are markedly different. A pass play is a study in contrasts; it leads to extremely variable outcomes.

What is a frequency chart?

The frequency chart is referred to as a point-and-figure chart and was created out of a need for floor traders to take note of price action and to identify trends. The y-axis is the variable measured, and the x-axis is the frequency count. Each change in price action is denoted in Xs and Os.

What Z-score is 3 points lower than the sample mean?

A score that is 3 points lower than the sample mean has a z-score of z = -0.25, and a score of X = 44 has a z-score of -0.75. What is the sample mean? M = 53 Which position in a distribution corresponds to a z-score of z = -1.00? below the mean by 1 standard deviation Tom scores an X = 43 on an exam with a mean of µ = 52.

What is the mean of a score equal to the mode?

No individual has a score exactly equal to the mode. One sample with n = 4 scores has a mean of M = 12, and a second sample with n = 6 scores has a mean of M = 8. If the two samples are combined, what is the mean for the combined set of scores? M = 9.6

Why do analysts use frequency distribution?

Analysts often use frequency distribution to visualize or illustrate the data collected in a sample. For example, the height of children can be split into several different categories or ranges. In measuring the height of 50 children, some are tall and some are short, but there is a high probability of a higher frequency or concentration in ...

What is frequency chart?

Investment houses still use the approach, which requires considerable practice, to teach traders. The frequency chart is referred to as a point-and-figure chart and was created out of a need for floor traders to take note of price action and to identify trends.

What does the column on a histogram mean?

The columns represent the number of children observed with heights measured in each interval. In general, a histogram chart will typically show a normal distribution, which means that the majority of occurrences will fall in the middle columns.

What is descriptive statistics?

Statistics provide a way to summarize and interpret behavioral observations. Descriptive statistics, such as measures of central tendency, measures of variability, and graphical representations of data, summarize observations. Central tendency can be measured with the mean, median, or mode. The mean, the most common measure, has the advantage of considering the specific value of every score in the distribution. The median is often appropriate when the distribution of scores is skewed or contains a few extreme scores. The mode can be used when the data are measured on a nominal scale of measurement. Variability is most often measured using standard deviation, which provides an indication of how far, on average, scores are from the mean.

What is the term for a statistical hypothesis that the experimenter expects to reject?

One is a statistical hypothesis that the experimenter expects to reject. It is referred to as the null hypothesis
