What is statistical control?
A statistical technique used to eliminate variance in dependent variables caused by extraneous sources. In evaluation research, statistical controls are often used to control for possible variation due to selection bias by adjusting data for program and control group on relevant characteristics.
Is race a categorical variable?
Yes, race is considered a categorical variable because it represents distinct groups or categories based on shared physical, cultural, or social characteristics. Categorical variables can be nominal, where there is no inherent order (e.g., different racial groups), or ordinal, where categories have a meaningful order. In statistical analysis, race is often used to categorize individuals for various studies and comparisons.
What is pooled variance T- test?
The pooled variance t-test is a statistical method used to compare the means of two independent groups when the variances of the two groups are assumed to be equal. It combines the variances from both groups into a single estimate, providing a more accurate measure of variability. This test calculates a t-statistic, which is then compared against a critical value from the t-distribution to determine if the difference between the group means is statistically significant. It’s commonly used in experimental and observational studies where sample sizes are small and variances are similar.
What are often used on graphs to show statistical comparison?
Error bars are often used on graphs to show statistical comparisons.

What is involved with statistical quality control?
Statistical quality control involves using statistical methods to monitor and improve the quality of products and processes. This includes collecting and analyzing data, setting quality standards, identifying sources of variation, and implementing strategies to reduce defects or errors. Statistical tools like control charts, hypothesis testing, and regression analysis are commonly used in statistical quality control.
Do you have a control group when you use qualitative writing?
Control groups are more commonly used in quantitative research to compare outcomes with a standard or no treatment group. In qualitative research, control groups are not typically utilized since the focus is on exploring experiences, perspectives, and meanings rather than testing hypotheses with controlled variables. The emphasis is on in-depth understanding rather than statistical generalizability.
Is ANOVA a qualitative or quantitative statistical analysis method?
ANOVA, which stands for Analysis of Variance, is a quantitative statistical analysis method used to compare means of three or more groups.
What is t Test?
t-test is the statistical test used to find the difference of mean between two groups
What statistical test should be used to compare the means of two groups: t test or chi-square?
A t-test should be used to compare the means of two groups, while a chi-square test is used to compare frequencies or proportions between groups.
Areas in businesses where statistics are used?
1.Agriculture: studies on the method for increasing the yields of crops. 2.Business: predict sales volumes and consumer reactions to new products 3.Industry: in quality control 4.sociology: comparative studies of different socioeconomics and cultural groups.
What percent of grade 8 students have not used marijuana?
Approximately 90% of grade 8 students have not used marijuana, based on statistical data from surveys and research studies.
What are control charts used for?
Control charts (also commonly called process-behaviour charts or Shewhart charts) are charts which are used to find out if a business or manufacturing process is in a state of statistical control. They were invented by Walter A. Shewhart in 1920.
