Type of data that contains descriptions like color, shape, smell, or texture.

• Qualitative Data

• Quantitative Data

Multiple Choice

Type of data that contains numbers.

• Qualitative Data

• Quantitative Data

Multiple Select

Scatter plots are a good data display because...

• They show the percentage of the whole data set.

• They allow you to see a correlation from a set of imperfect data points.

Multiple Select

Stem and leaf plots are a good data display because...

• They break down large numbers into groupings

• They show the correlation of a data set (positive or negative)

Multiple Select

Histograms are good data displays because...

• They allow you to group your data values into a range of numbers

• They allow you to make a prediction of a future measurement

Multiple Select

Pie charts are a good data display because...

• They show the correlation of points

• They show the percentages of the whole data set

Multiple Choice

• correlation

• t test

• descriptive statistics

• ANOVA

Multiple Choice

How can outliers affect data interpretation?

• Outliers can improve the accuracy of statistical measures and enhance data interpretation.

• Outliers have no impact on statistical measures and data interpretation.

• Outliers can distort statistical measures and introduce bias into data interpretation.

• Outliers can only affect qualitative data interpretation, not quantitative data interpretation.

Multiple Choice

What are some limitations of data tables in data analysis?

• Limited ability to handle complex relationships between variables, difficulty in representing unstructured or qualitative data, and challenges in handling missing or incomplete data.

• Difficulty in visualizing data trends

• Limited computational power for large datasets

Multiple Choice

Explain the concept of correlation in data analysis.

• Correlation measures the strength of causation between variables.

• Correlation is a measure of the average difference between variables.

• Correlation determines the direction of the relationship between variables.

• Correlation measures the statistical relationship between variables.

Multiple Choice

A researcher has completed several experiments to test a new medicine, and his conclusions show that he might have found a cure for a serious disease. What is the next thing the researcher should do?

• communicate his results to other scientists so they can repeat his

  experiments

• make sure no other researchers know about his results so he can

  become famous

• tell other scientists his experiments were not successful so they will

  do their own experiments

• refuse to share his data with anyone because they might not agree

  with him

Multiple Choice

A research scientist became famous for making a new scientific discovery. When other scientists repeated the experiment, they did not get the same results. What should the other scientists do?

  been made

• tell everyone that the research scientist must be wrong

• analyze the data from all the experiments to look for reasons for the

  difference
